Key Topics Covered
Introduction to Parallel Testing:
The video begins by explaining the concept of parallel testing, where multiple tests are run simultaneously instead of sequentially. This reduces test execution time significantly.
WebdriverIO and Parallel Testing:
WebdriverIO allows up to 10 tests to run concurrently. It runs each spec file in parallel within a single session by default.
Benefits of Parallel Testing:
The main benefit of parallel testing is that it saves time. For example, running 10 tests sequentially would take around 60 seconds, but running them in parallel would only take 6 seconds, thus saving approximately 90% of the time.
Sequential vs. Parallel Testing:
Sequential testing runs tests one after another, while parallel testing runs multiple tests at once. The number of tests running in parallel is limited only by the available resources (e.g., CPUs).
WebdriverIO Configuration:
The configuration file (wdio.conf.js) is used to set the number of tests that can run in parallel. By adjusting the Max Instances setting, you can control how many spec files run at the same time.
Example in Code:
The video provides examples where spec files are run in parallel using WebdriverIO. It demonstrates how to configure the tests in the wdio.conf.js file to allow multiple tests to run simultaneously.
Practical Implementation:
Marco demonstrates setting up a project with parallel testing, showing how the tests execute in parallel in the LambdaTest platform.
Considerations and Limitations:
Marco discusses the limitations of parallel testing, such as resource constraints. For example, the LambdaTest plan used in the video allows only two tests to run concurrently.
