Filters for Espresso Tests

---

Usually, all the test cases of your Espresso test suite are executed, but there is a way to filter these. You can use Espresso test runner (typically AndroidJUnitRunner), which provides you with multiple options to filter the test cases which you want to execute.

To filter the test cases, you just need to pass the suitable parameters in LambdaTest’s REST API request. Refer to the table below to understand how to use various filters provided by LambdaTest.

Given below is the REST API endpoint:

POST   /framework/v1/espresso/build

Parameters	Description	Values	Datatype
package	Allows the user to only run specific packages defined	Multiple packages can be passed in comma-separated format. E.g. [“com.example.proverbial.packagename”]	Array
skipPackage	Allows the user to run all packages except the ones defined	Multiple packages can be passed in comma-separated format. E.g. [“com.example.proverbial.packagename”]	Array
class	Allows the user to only run specific classes defined	Multiple classes can be passed in comma-separated format. E.g. [“com.example.proverbial.packagename.classname”]	Array
skipClass	Allows the user to run all classes except the ones defined	Multiple classes can be passed in comma-separated format. E.g. [“com.example.proverbial.packagename.classname”]	Array
annotation	Allows the user to only run specific annotations defined	Only a single annotation can be passed. E.g. ”com.example.proverbial.annotation”	String
skipAnnotation	Allows the user to run all annotations except the ones defined	Only a single annotation can be passed. E.g. ”com.example.proverbial.annotation”	String
size	Allows the user to run only tests that are annotated with the matching size value @SmallTest, @MediumTest or @LargeTest	You may specify only one value for this property from the three valid values i.e. “small”, “medium”, “large”	String

Note

You can not use the following filters simultaneously.

• class and package
• class and skipClass
• annotation and skipAnnotation
• package and skipPackage

Some Examples

Please refer to the example cURL requests given below for your reference.

1. To run specifically defined packages

MacOS/Linux

curl --location --request POST 'https://mobile-api.lambdatest.com/framework/v1/espresso/build' \
        --header 'Authorization: Basic <Enter_Basic_Auth>' \
        --header 'Content-Type: application/json' \
        --data-raw '{
            "app" : "lt://APP_ID",
            "testSuite": "lt://TestSuite_ID",
            "device" :  ["Pixel 6-12"],
            "queueTimeout": 360,
            "IdleTimeout": 150,
            "deviceLog": true,
            "build" : "Proverbial-Espresso"
            “package” : [“com.example.proverbial.packagename1”,"com.example.proverbial.packagename2"] 
            }'
