如何在Android Studio中调试单个robolectric单元测试

Question

I am able to debug my android gradle project if I run all the unit tests using the following steps:

First configure IDE With a Gradle Run/Debug config for Unit Testing Using Robolectric & JUnit

1. in IDE menu do: File / Settings / Compiler / Gradle : Uncheck "Use in-process build"
2. In IDE do: Run / Edit Configuration / + / Gradle
3. Enter the following data in fields: Name: test , Gradle project: .../app/build.gradle, Tasks: test, Script parameters: --debug --stacktrace

Next, to run / debug tests from IDE do:

1. Choose "test" from configuration
2. To Run: Run / Run 'test'
3. To Debug: Run / Debug 'test'

This allows me to run all the tests in the debugger.

I am now looking to find a way to do the same but for a single specified test only. Any suggestions how would be great.

It depends on the version of gradle you are using. If you are using version 1.x, then add the following script parameter to your run configuration

-Dtest.single=<testfilename> 

eg

-Dtest.single=MyTest

You don't have to worry about the path to the file - just the name of the file containing the test class without the trailing .java

If you are using gradle 2.x, then add the following script parameter to your run configuration

--tests <test class name>

eg

--tests com.example.data.MyTest

or --tests *.MyTest

With wildcards you can run not just one test but a subset of your tests

--tests com.example.data.*
