单元测试的时候报错 junit.framework.AssertionFailedError: No tests found in androidstudio.kodulf.unittestdemo2.TestCaseDo at junit.framework.Assert.fail(Assert.java:50) at junit.framework.TestSuite$1.runTest(TestSuite.java:97) at junit.framework.TestCase.runBare(TestCase.java:134) at junit.framework.TestResult$1.protect(TestResult.java:115) at android.support.test.internal.runner.junit3.AndroidTestResult.runProtected(AndroidTestResult.java:77) at junit.framework.TestResult.run(TestResult.java:118) at android.support.test.internal.runner.junit3.AndroidTestResult.run(AndroidTestResult.java:55) at junit.framework.TestCase.run(TestCase.java:124) at android.support.test.internal.runner.junit3.NonLeakyTestSuite$NonLeakyTest.run(NonLeakyTestSuite.java:63) at junit.framework.TestSuite.runTest(TestSuite.java:243) at junit.framework.TestSuite.run(TestSuite.java:238) at android.support.test.internal.runner.junit3.DelegatingTestSuite.run(DelegatingTestSuite.java:103) at android.support.test.internal.runner.junit3.AndroidTestSuite.run(AndroidTestSuite.java:69) at android.support.test.internal.runner.junit3.JUnit38ClassRunner.run(JUnit38ClassRunner.java:103) at org.junit.runners.Suite.runChild(Suite.java:128) at org.junit.runners.Suite.runChild(Suite.java:27) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at org.junit.runner.JUnitCore.run(JUnitCore.java:115) at android.support.test.internal.runner.TestExecutor.execute(TestExecutor.java:59) at android.support.test.runner.AndroidJUnitRunner.onStart(AndroidJUnitRunner.java:262) at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1701)

Tests ran to completion.

这个报错最后发现原因是我的方法名是首字母大写的了

public class TestCaseDo extends TestCase {    public void TestMax(){        int max = TestClass.max(0, 1);        assertEquals(max,1);    }}

解决办法：

方法名首字母小写

public class TestCaseDo extends TestCase {    public void testMax(){        int max = TestClass.max(0, 1);        assertEquals(max,1);    }}
