嗨，我是单元测试的新手。我正在为一个库项目编写单元测试用例。我的库仅包含异步网络调用。我曾尝试使用robotium 和android 仪器框架来编写测试用例。我收到以下错误
----- begin exception -----
I/TestRunner( 1578):

每当条件失败时，例如：assertTrue(false)并且执行突然停止。它必须执行其他测试用例对吗？或者我做错了什么请帮忙。
这是我的测试用例
public void test1AddDecimalValues() {
String mathResult = "80";
assertTrue("Add result should be " + "100" + " but was "
+ mathResult, mathResult.equals("100"));
}
