1. The test class must be extends androidtestcase.
2. the test method must start with test and throw an exception.
3. Create a new class to be tested in the test method, and then test its function.
(Often usedAssert. assertequals (A, B );)
PackageCom. Zhy. junitexample. test;ImportCom. Zhy. servers. server;ImportAndroid. Test. androidtestcase;Public ClassServertestExtendsAndroidtestcase {Public VoidTestsave ()ThrowsException {server Ser=NewServer (); Ser. Save ();}}
4. In androidmainfest, add
<Uses-library Android: Name = "android. Test. Runner"/>
Join Test Database
<Instrumentation
Android: Name = "android. Test. instrumentationtestrunner"
Android: targetpackage = "com. Zhy. junitexample"/>
Note Android: targetpackage is the package in the project of the class you want to test (open its androidmainfest and you will see it), not the specific package name in the project.
