在Android 19及更低版本上使用JunitParams运行程序时出现异常。
以下测试套件将重现问题
@RunWith(JUnitParamsRunner.class)
public class SimpleTest {
@Test
@Parameters({ "false", "true" })
public void simpleParameterizedTest(boolean enabled) {
// Should execute and pass
}
}
测试应该执行并通过。
测试没有运行,因为"没有找到测试"
我检查了日志,发现以下异常。

我们刚刚在JUnitParams中解决了这个问题并发布了新版本。
现在您可以获取最新版本并开始在Android 19及更低版本中使用它!
androidTestCompile 'pl.pragmatists:JUnitParams:1.1.1'

在Studio的较新版本中,您需要编写:
testImplementation 'pl.pragmatists:JUnitParams:1.1.1'
但androidTestImplementation ...
不起作用。
