tru*_*-mt 18 android android-espresso
我的设置: - 带有手机和平板电脑版本的Android应用程序 - 我正在使用Android Espresso进行UI测试(现在仅用于手机版,在buildagent上使用手机)
我想做什么: - 现在我希望Espresso区分手机和平板电脑的测试 - 所以测试A应该只能通过平板电脑执行,测试B应该只能通过手机和测试C执行 - 测试应该可以通过gradle任务

三个选项,所有这些选项都可以通过gradlew connectedAndroidTest自定义gradle任务执行:
org.junit.Assume从假设与假设 - junit-team/junit Wiki - Github:
默认的JUnit运行器将失败假设的测试视为忽略.自定义跑步者可能表现不同.
不幸的是,android.support.test.runner.AndroidJUnit4(com.android.support.test:runner:0.2)运行器将失败的假设视为失败的测试.
修复此行为后,以下操作将起作用(请参阅下面的选项3以获取isScreenSw600dp()源代码):

具体测试方法
@Test
public void testA() {
assumeTrue(!isScreenSw600dp());
// test for phone only
}
@Test
public void testB() {
assumeTrue(isScreenSw600dp());
// test for tablet only
}

这导致我们创建了一个ConditionalIgnore注释和一个相应的规则来将它挂钩到JUnit运行时.事情很简单,最好用一个例子来解释:
public class SomeTest {
@Rule
public ConditionalIgnoreRule rule = new ConditionalIgnoreRule();
@Test
@ConditionalIgnore( condition = NotRunningOnWindows.class )
public void testFocus() {
// ...
}
}
public class NotRunningOnWindows implements IgnoreCondition {
public boolean isSatisfied() {
return !System.getProperty( "os.name" ).startsWith( "Windows" );
}
}

ConditionalIgnoreRule这里的代码:JUnit规则有条件地忽略测试用例.
可以轻松修改此方法以实现isScreenSw600dp()下面选项3中的方法.
这是最不优雅的选项,特别是因为完全跳过的测试将被报告为已通过,但它很容易实现.这是一个完整的示例测试类,可以帮助您入门:
