uiautomator 自定义testrunner使用和启动原理

继承testrunner实现runner

public class TestRunner extends UiAutomatorTestRunner
{
    private final List<String> mTestClasses = new ArrayList<String>();
 
    @Override
    public void run(List<String> testClasses, Bundle params, boolean debug, boolean monkey)
    {
        try
        {
            testClasses.removeAll(testClasses);  //removeAll
            addTestClasses();
            testClasses.addAll(mTestClasses); //addAll
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        super.run(testClasses, params, debug, monkey);
}

运行testrunner

-e runner com.meizu.browser.test.TestRunner

应用

可以根据外部传入的值，来确定需要执行什么用例

例如-e priority p1  取出priority值，在addtestcase的时候只加入priority是P1的testcase
