Run Sample Program with junit-4.12.jar
How to run sample program with junit-4.12.jar? I have Calculator.java and the JUnit test program, CalculatorTest.java ready.
✍: FYIcenter.com
junit-4.12.jar is the version 4.12 of JUnit JAR library file.
It requires hamcrest-core-1.3.jar.
To run the JUnit test program, CalculatorTest.java, you need launch the org.junit.runner.JUnitCore class and specify the test program class as the parameter:
\fyicenter>java -version java version "1.8.0_45" \fyicenter>java -cp .;\local\lib\junit-4.12.jar; \local\lib\hamcrest-core-1.3.jar org.junit.runner.JUnitCore CalculatorTest JUnit version 4.12 .E..E Time: 0.007 There were 2 failures: 1) testFraction(CalculatorTest) junit.framework.AssertionFailedError: expected:<5> but was:<4> at junit.framework.Assert.fail(Assert.java:57) at junit.framework.Assert.failNotEquals(Assert.java:329) at junit.framework.Assert.assertEquals(Assert.java:78) at junit.framework.Assert.assertEquals(Assert.java:234) at junit.framework.Assert.assertEquals(Assert.java:241) at junit.framework.TestCase.assertEquals(TestCase.java:409) at CalculatorTest.testFraction(CalculatorTest.java:12) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at junit.framework.TestCase.runTest(TestCase.java:176) at junit.framework.TestCase.runBare(TestCase.java:141) at junit.framework.TestResult$1.protect(TestResult.java:122) at junit.framework.TestResult.runProtected(TestResult.java:142) at junit.framework.TestResult.run(TestResult.java:125) at junit.framework.TestCase.run(TestCase.java:129) at junit.framework.TestSuite.runTest(TestSuite.java:252) at junit.framework.TestSuite.run(TestSuite.java:247) at org.junit.internal.runners.JUnit38ClassRunner.run (JUnit38ClassRunner.java:86) 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 org.junit.runner.JUnitCore.runMain(JUnitCore.java:77) at org.junit.runner.JUnitCore.main(JUnitCore.java:36) 2) testSubtraction(CalculatorTest) java.lang.NumberFormatException: For input string: "10-1" at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:2043) at sun.misc.FloatingDecimal.parseFloat(FloatingDecimal.java:122) at java.lang.Float.parseFloat(Float.java:451) at java.lang.Float.valueOf(Float.java:416) at Calculator.evaluate(Calculator.java:6) at CalculatorTest.testSubtraction(CalculatorTest.java:16) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at junit.framework.TestCase.runTest(TestCase.java:176) at junit.framework.TestCase.runBare(TestCase.java:141) at junit.framework.TestResult$1.protect(TestResult.java:122) at junit.framework.TestResult.runProtected(TestResult.java:142) at junit.framework.TestResult.run(TestResult.java:125) at junit.framework.TestCase.run(TestCase.java:129) at junit.framework.TestSuite.runTest(TestSuite.java:252) at junit.framework.TestSuite.run(TestSuite.java:247) at org.junit.internal.runners.JUnit38ClassRunner.run (JUnit38ClassRunner.java:86) 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 org.junit.runner.JUnitCore.runMain(JUnitCore.java:77) at org.junit.runner.JUnitCore.main(JUnitCore.java:36) FAILURES!!!
