32 Top Java Frameworks For 2024

In today’s world, quality is the key to success for any product software. Human mistakes by programmers are inevitable, but the cost of not correcting them in time can be costly and lead to debts. Technical debt is way riskier than financial debt! Unaddressed technical debt can destroy the product.

One bibliometric study published in August 2022 at the University of Maribor showed that the research publications related to software quality are currently following an exponential growth trend and that the software quality research community is growing tremendously. Quality today is at the forefront of product development.

In this article on top Java frameworks, let’s delve into the various Java testing frameworks and discuss some of the most popular Java frameworks used for web development with their salient features.

Introduction

Automation testing has been there for a while and is widely adopted by small-scale startups to large enterprises. Automating the test cases for AUT (Application Under Test) is essential to get a quick quality assessment before any new release. Delivering new features without compromising on quality needs good test automation coverage. And to achieve that, we must make good use of some test frameworks readily available on the Internet. Chosen automation testing framework should align well with the internal test processes.

According to the StackOverflow 2023 survey, Java holds the top 6th position, with 29.97% of people successfully using it. It is a reliable programming language that can be harnessed to its full potential with Java testing frameworks. There are many Java frameworks in the market to cater to different needs. It’s not easy to pick and choose one.

What is Framework in Java?

In Java, a framework is a pre-written set of classes, interfaces, and methods that provide a structure to build applications. It offers a foundation for developers to create software by providing reusable components, libraries, and guidelines. Frameworks simplify development by offering ready-made solutions for common tasks, allowing developers to focus more on application-specific logic rather than reinventing the wheel. They often enforce certain design patterns, best practices, and conventions, which can enhance productivity and maintainability of Java applications.

9 Best Java Testing Frameworks

Java testing frameworks are essential for ensuring the quality of software applications. Several popular Java frameworks are available that cater to different testing needs. Here are some of the commonly used Java testing frameworks in detail.

1. JUnit

JUnit is a Java framework for automating unit tests. Usually, a developer who builds a unit or API must ensure detailed unit testing. JUnit has various test guidelines, which can help developers build reliable unit tests. As application development advances, the volume of APIs will grow exponentially.

It helps to manage all these unit tests effectively. Also, since it’s about testing a single unit, tests are incredibly reliable and would help us build a firm test bed as the code grows. When writing this blog, the JUnit version referred to is 5.6.2.

In earlier JUnit versions, we must import a single monolithic jar with the whole JUnit architecture. For example, APIs for writing and running tests were part of the same jar. JUnit 5, however, allows us to import what is necessary. The API for writing tests using JUnit is called JUnit Jupiter. And the API for managing and running tests is called JUnit Platform.

Why is JUnit One of the Best Java Frameworks for Testing?

JUnit offers a wide range of features that facilitate the creation and execution of effective unit tests. Some of the key features that make JUnit one of the best Java frameworks are:

• Support for Annotations

JUnit 5 has a wide range of annotations that programmers can use in their code. It improves the readability of code. Below are some of the most used JUnit Annotations.

Annotations	Usage
@Test	Denotes that a method is a test method.
@DisplayName	User-friendly method name, which would be displayed in the report.
@BeforeEach	Methods with this annotation will be executed before each test.
@AfterEach	Methods with this annotation will be executed after each test.
@BeforeAll	Methods with this annotation will be executed before all tests.
@AfterAll	Methods with this annotation will be executed after all tests.
@RepeatedTest	Allows a test method to be repeated a specified number of times during test execution.
@Disabled	Methods with this annotation will not be executed.

• Assertions for testing particular conditions

JUnit Assertions are used to test a particular condition that must be evaluated to be true for the test to continue. Adding plenty of positive and negative boundary-level unit tests is an important part of the JUnit test suite. Assertions such as assertEquals, assertNotEquals, etc., help implement positive and negative test scenarios.

Here are some of the most used assertions of JUnit 5

Assertion Type	Usage
assertEquals(expected, actual)	Asserts that expected and actual values are equal. Both expected and actual values should be of the same data type.
assertNotEquals(unexpected, actual)	Asserts that expected and actual values are not equal. Both expected and actual values should be of the same data type.
assertTrue(boolean condition)	Asserts that the supplied condition is true.
assertFalse (boolean Condition)	Asserts that the supplied condition is not true.
assertAll(Executable… executables)	Asserts that all supplied executables do not throw exceptions.
assertSame(Object expected, Object actual)	Asserts that expected and actual reference to the same object.
assertArrayEquals(expected[], actual[])	Asserts that expected and actual arrays are equal. An array could be of any datatype, e.g., Char, String, Boolean, etc.
assertNotNull(Object actual)	Asserts that actual is not null.
assertNotSame(Object unexpected, Object actual)	Asserts that expected and actual do not refer to the same object.

• Test Runner for results

For running unit tests developed using JUnit 5, we need to import the JUnit Platform. For IDEs such as IntelliJ IDEA 2016.2 + and Eclipse Oxygen.1a (4.7.1a +). We can also explicitly import libraries of the JUnit Platform into Maven and Gradle to run the tests. Once desired libraries are imported into Maven or Gradle repositories, we can use commands to perform JUnit testing.

For the Maven command, we can use:

mvn clean test

1	mvn clean test

For Gradle, we can use:

gradle clean test

1	gradle clean test

• Multi-threading

With JUnit 5, you can use multiple test runners simultaneously to run your tests. This helps us distribute tests for faster test execution. Furthermore, you may also check out our comprehensive guide on JUnit 5 extensions.

To enable parallel testing with JUnit 5 and Selenium, we must create a junit-platform.properties file in the src/test/resources folder. We can enable the parallelization feature by adding the following line in the file as mentioned above:

We can also add the below lines in the above file to enable multithreading at the class and module level.

To run tests parallel within a particular class in separate Thread	junit.jupiter.execution.parallel.mode.default = concurrent
To run tests parallel within a particular module in separate Thread	junit.jupiter.execution.parallel.mode.classes.default = concurrent

Usage of JUnit Framework

Now that we have looked into the key features of JUnit 5, let’s see this popular Java framework in action!

Add these entries to the POM file to use JUnit 5 Platform and Junit 5 Jupiter.

Sample JUnit Code snippet with different JUnit annotations and assertions:

Let’s now see how to run JUnit 5 tests using IntelliJ (2020.2 version).

Right-click on the test and select the ‘Run ‘junit’’ option as shown below.

After execution, it would show test results as shown below.

For running JUnit tests using Maven, open a command prompt (Windows), navigate to the directory where you have the JUnit test project copied, and enter the following command:

Once executed, it should show output as below.

When to Opt for the JUnit Framework?

• For building a unit test suite right from the initial development phase.
• For testing the behavior of a particular unit.
• For better coordination between developers and testers.

2. Selenium

Selenium is a browser automation tool for web-based applications. It is the most popular open-source automation testing tool for integration test cases. It is used mainly for the UI automation of test cases.

Selenium comes with Selenium WebDriver, Selenium Grid, and many other useful features essential for building efficient automation tests on any browser. You can also perform Selenium automation testing with Selenide framework.

It has a good online presence, making it easy for automation engineers with beginner-level experience to adapt. When writing this blog on Java frameworks, the Selenium version is 4.8.3.

Why is Selenium One of the Best Java Frameworks for Testing?

Let’s delve into the salient features of Selenium and uncover why is it one of the prominent Java frameworks:

• Selenium WebDriver with strong web support

Selenium WebDriver is the API that establishes the communication between the test script and the browser. Each browser would have its corresponding WebDriver. WebDriver supports a wide range of methods to interact with browsers. Below are some of the most common WebDriver methods used.

Methods	Purpose
driver.get("https://www.lambdatest.com/blog/")	To open any URL.
driver.navigate().to("https://accounts.lambdatest.com/login");	To navigate to another URL.
driver.navigate().refresh();	To refresh the page.
driver.findElement(By.id("login-button")).click();	To locate any UI element.
driver.switchTo().frame("iframeName");	To switch to any nested iframe.
driver.navigate().back();	To navigate back in the browser.
driver.navigate().forward();	To navigate forward in the browser.
driver.switchTo().window("Child Window name");	In case of multiple browser windows, to switch to a specific window.

• Support for multi-browser testing

Selenium interacts with UI via a web browser. Using a browser with native support, it can perform any operation just like an end user would. It supports most of the popular browsers. The list includes Chrome, Safari, IE, Opera, Firefox, Edge, etc. Features like the Page Object Model in Selenium Java (POM) can help maintain automation code with minimal effort.

• Support of multiple programming languages

Selenium supports all the major programming languages like Java, Python, JavaScript, PHP, Perl, Ruby, etc. We can write automation scripts in any language we are comfortable with.

• Selenium IDE

Selenium IDE provides a record and playback feature for building automation scripts. This tool comes in handy for those with limited programming skills. This IDE comes as a browser add-on. It is available for major browsers like Firefox, Chrome, etc.

• Better integration options

Selenium can be easily integrated with frameworks like Ant and Maven for source code compilation. It can also be integrated with TestNG for generating effective reports for Selenium test execution.

• A mature tool for UI automation

Selenium has been around since 2004 now. It has evolved into a tool with good features for automating any web UI test case. Also, being an open-source and widely used tool has resulted in a good online presence. Several communities can help users with any day-to-day automation challenges.

Usage of Selenium Framework

Let’s now assume a simple test case. If one wants to check if the LambdaTest account has been logged in successfully or not. He can write a script for the same using Selenium as below.

POM Entry

Sample Code

When to Opt for the Selenium Framework?

Here are some scenarios where opting for Selenium would be appropriate:

• To build a robust UI automation suite

With a comprehensive set of features, one can build a robust UI automation. As applications tend to change over time, we need to update test scripts. Selenium provides all support to build a suite that is easy to maintain.

• To get more accurate UI test results

UI tests tend to be flaky and unreliable due to numerous factors such as – application sluggishness and ever-changing application functionality. Selenium provides multiple methods to wait dynamically for a particular element to load. It also provides concepts such as Page Object Model (POM) to organize your tests.

3. TestNG

TestNG is a JUnit-based framework. It is one of the best Java frameworks for testing. However, it does have particular distinctions. Unlike JUnit, TestNG is designed for unit, integration, and end-to-end tests. In an enterprise organization, where we have a large set of automated test cases, we face the following challenges:

• How to create a subset or full set of tests for Build Verification tests (BVT), Sanity tests, Regression tests, etc.?
• How to run tests in the multi-threaded manner for quick execution?
• How to run specific test cases against a varied set of test data?
• How to make some tests dependent on other tests?
• How to disable tests owing to any open defects?
• How to generate good reports with all key execution details?

TestNG helps us solve the above crucial challenges. It helps us manage test execution better and more effectively. At the time of writing, the TestNG version referred to is 7.7.1.

Subscribe to our LambdaTest YouTube Channel for live updates with the latest tutorials around Selenium testing, Cypress testing, and more.

Why is TestNG One of the Best Java Frameworks for Testing?

Let’s dive into the special features of TestNG and discover why testers consider it as one of the best Java frameworks for testing:

• Multiple annotations

TestNG supports a wide range of annotations. These annotations can be used to set test execution patterns. Here is the list of the most commonly used TestNG annotations.

Annotations	Purpose
@BeforeSuite	Methods with this annotation will run before the execution of all the test methods in the suite.
@AfterSuite	Methods with this annotation will run after the execution of all the test methods in the suite.
@BeforeTest	Methods with this annotation will be executed before the execution of each test method from that class.
@AfterTest	Method with this annotation will be executed after the execution of each test method from that class
@BeforeClass	Methods with this annotation will be executed before the first method of the current class is invoked.
@AfterClass	Methods with this annotation will be invoked after the execution of all the test methods of the current class.
@BeforeMethod	Methods with this annotation will be executed before each test method runs.
@AfterMethod	Methods with this annotation will run after the execution of each test method.
@BeforeGroups	Methods with this annotation will run only once for a group before the execution of all test cases belonging to that group.

In addition to this, you may refer to our complete guide on TestNG annotations.

• Grouping of tests

TestNG helps you form ‘test groups’. And it can be configured separately in the configuration file. This means we can create test suites outside test scripts as per our needs.

For e.g., in a script, we can group test cases as shown below:



During run time, in TestNG.xml, we can specify the group that needs to run.



The above file will run only ‘TestCase2’ from the above class.

• Easy to configure dependent tests

Sometimes, we must ensure the execution of certain tests before other tests. We can ensure that by introducing dependency between such tests. TestNG provides an easy way to accomplish that.



• Parameterized tests

It’s a common requirement where we want to run the same tests against different sets of test data. TestNG provides us with a cleaner way to do that.

We can define parameterized tests using TestNG, as shown below.

In test script:



In the test suite file, TestNG.xml



• Multi-threaded execution

Test cases run in parallel for quick execution. We can have multithreading at method, test, and class levels. Accordingly, the TestNG.xml test suite file can be configured as below. Based on the level of multithreading, we can pass parallel values as ‘methods,’ ‘tests,’ and ‘classes.’ If we have dependent tests, we must be careful in introducing multithreading as it might not work as expected. Accordingly, the TestNG.xml test suite file can be configured as shown below.



• A retrial of failed test cases:

Every time tests fail in a suite, TestNG creates a testng-failed.xml file in the output directory. This XML file contains the necessary information to rerun only those methods that failed. It allows users to quickly reproduce the failures without rerunning all the tests.

• Support for test reports

Reporting is a key data point for any test execution. TestNG, by default, generates an HTML and an XML report. The report gets generated in the target folder of the project. TestNG also allows us to generate our reports. For that, we can make use of either org.testng.ITestListener or org.testng.IReporter interface.

Here is a sample snapshot of an HTML report in TestNG:

Usage of the TestNG Framework

To use TestNG, add the entry below to your pom file.

With TestNG, the script looks like below. As you can see, the main function is no longer required. TestNG will execute the test method with @Test annotation.

We can also create a test suite file using TestNG, as per our needs.

When to Opt for the TestNG Framework?

As the test suite grows in size, management of tests could get tedious if not handled properly. Test execution is completely different from test development and has its own challenges. TestNG helps address most of it.

4. JGiven

JGiven is considered one of the best Java frameworks for testing. Sometimes, even though we have thousands of automated tests, it doesn’t give confidence in the quality of the test scripts written. Business Analysts who draft the requirement can’t read through test scripts to understand the actual test coverage. JGiven is the Java framework for automating Behaviour Driven Development (BDD) tests.

Unit testing, Integration, and end-to-end of any type of use cases can be implemented in BDD using JGiven. The BDD approach forces testers to be in the customer’s place. Since test scripts are written in Gherkin format, even a non-coder can read the test script and find out what it is doing. Thus, reducing the communication gap between expected business features and their actual implementation. At the time of writing, the JGiven version referred to is 1.2.5.

Why is JGiven One of the Best Java Frameworks for Testing?

JGiven offers several key features that aim to enhance the tests. Below are some of the notable ones:

• Aligns product development with Business values

Business Analysts (BAs) draft requirements or scenarios in plain English. Product development translates it into code & further moves ahead for testing. This process does create problems. During development, some key details highlighted by BAs can get lost in translation. JGiven helps us overcome that.

Scenarios are written in plain Java by BAs with a fluent Java framework API. Business Analysts thus dictate the structure of the final automated test case and not the automation engineer. Automation engineers just have to fill in the code in the structure. This helps in reducing the communication gap between the two ends.

For e.g., the Login scenario will be defined by BAs as shown below.



• Integration support for JUnit, TestNG

JGiven Scenarios can be executed using either JUnit or TestNG. No extra test runner is required. JGiven works well with existing IDEs such as Eclipse, IntelliJ, etc.

• Test report

After the test scenario is executed, reports are generated by converting the scenario into plain English. Since Business Analysts originally draft the scenario, the test report becomes a living documentation.

For aforementioned scenario, the report in the plain test will look like this:

Test Lambdatest login

Given open URL: https://accounts.lambdatest.com/login

When login to LambadaTest

Then, verify login is successful

With the above report, JGiven can also generate an HTML report.



• Pass percentage gives more accurate quality perception

Business Analysts define scenarios in plain Java, and they hand it over to the test team. Testers have to implement each method defined by Business Analysts. This ensures good test coverage and instills discipline in the test script. The execution report of such a test suite will also give the correct quality perception.

Usage of the JGiven Framework

For using JGiven with TestNG, add the below entry to the POM file.

Initially, Business Analysts will give use case drafted as below:

You can see the division of the test above into three stages: Given, When and Then. This allows the separation logic of the test into individual classes. Each stage is a class-expanding stage. Testers must write stage classes for Given, When, and Then as below,

When to Opt for the JGiven Framework?

JGiven is a difficult Java framework to adopt, let’s face it! However, it solves an important problem of ensuring good test coverage. We can use it to automate a few but ‘must-work’ critical business use cases.

We have explored some of the Java frameworks in detail. Certainly, some more frameworks offer efficient approaches and enable developers to improve overall software quality. Let’s have a brief walkthrough.

5. Selenide
