我用 android studio 创建了一个仪器测试,使用 Express Record Test。

流程:
-> 从 Activity_splash_screen 类开始。
-> 然后 LoginActivity.java 屏幕进入屏幕。
-> 在登录屏幕转到另一个要求 DDI、电话和用户 ID 的活动 (ValuesPeternActivity.java) 之后。
在 HomeActivity.java 中结束流程

1°测试填写登录名和密码字段;(成功)
2°点击下一个标题进入新屏幕;(成功)
3° 发生错误,因为它停在 txtDDI 字段中,这是第二个屏幕上的第一个字段。(错误)

如果我坚持反复执行,有时测试通过,有时甚至第一次屏幕测试都没有通过。我相信它表征了 express 和 thread 之间缺乏同步。

如何同步?
我发现了它,但我无法实现它。查看链接-> IdlingRegistry 和 Espresso 将等待资源

我看到一个视频,其中那个人正在做这个测试并且不需要任何测试。一定是因为androidx,只能!

错误的错误:

在这里我必须放置 editText.check (matches (withText (endsWith ("joseb@gmail.com"))))。
endWidth 帮助只取必要的东西,因为我在这里犯了一个错误。
