JUnit4参数化测试不同Android SDK版本

Question

I'd like to test a function having a conditional statement for different Android SDK build versions with some parameters. The function looks like:

if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.O) {
    // do something with parameter(s) and return it;
} else {
    // do something with parameter(s) and return it;
}

I can use Parameterized.class runner or JUnitParams to get it run with a set of parameters. I can also create a single test function and can change the SDK_INT field and call the function to test. But I was not able to combine both approaches into the same unit test class.

Is there any annotation to set the SDK for a particular test method? Or what is the best approach to test functions like the above?

Answer 1

A simple yet not elegant solution is to use the Enclosed runner and inner classes changing the SDK_INT field in a function annotated with @BeforeClass .
