junit3

I'm attempting to run a simple JUnit test case on version 3.7 of JUnit (I'm not able to upgrade this to the latest version) Running IntelliJ, I get the following exception when I attempt to run my JUnit testcase : Exception in thread "main" java.lang.NoClassDefFoundError: junit/textui/ResultPrinter at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:169) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:108) Caused by: java.lang.ClassNotFoundException: junit.textui.ResultPrinter at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java

I want to back up my application's database before replacing it with the test fixture. I'm forced to use Junit3 because of Android limitations, and I want to implement the equivalent behavior of @BeforeClass an @AfterClass. UPDATE: There is now a tool ( Junit4Android ) to get support for Junit4 on Android. It's a bit of a kludge but should work. To achieve the @BeforeClass equivalent, I had been using a static variable and initializing it during the first run like this, but I need to be able to restore the database after running all the tests. I can't think of a way of detecting when the last

I'm running JUnit via Ant using a target something like this: <target name="junit" depends="compile"> <mkdir dir="${report.dir}"/> <junit printsummary="yes" haltonfailure="yes" showoutput="yes" > <classpath> <path refid="classpath"/> <path location="${classes.dir}"/> </classpath> <formatter type="brief" usefile="false"/> <formatter type="xml"/> <batchtest fork="yes" todir="${report.dir}"> <fileset dir="${src.dir}" includes="**/*Tests.java" /> </batchtest> </junit> </target> I have a class like this: public class UserTests extends TestCase { public void testWillAlwaysFail() { fail("An error

as the documentation of Android says, "Note that the Android testing API supports JUnit 3 code style, but not JUnit 4." ( Testing Fundamentals ). It should be clear that JUnit 4 cannot be used out of the box with Android. But why is this the case? Is it because the tests are executed within the DVM (in that the Android Runtime only has support for JUnit 3)? On a JVM one on its own could choose the JUnit runtime that should be used. Isn't this possible within the DVM? Update 2015/10 It is now possible via the AndroidJUnitRunner, which is part of the Android Testing Support Library . In short,

Could someone describe in a few words what the main differences between JUnit 3 and 4 are? Paul Sanwald Java 5 annotations for setup and teardown ( @before and @after ) instead of setUp() and tearDown() . don't need to extend TestCase anymore. @Test annotation replaces testSomeMethod() naming convention. static imports for asserts. Junit theories, which allow you to separate data sets from the test itself. 来源： https://stackoverflow.com/questions/6685730/the-differences-between-junit-3-and-junit-4

When i run the below code, both test cases come true: import static junit.framework.Assert.assertEquals; import org.junit.Test; public class MyTest{ private int count; @Before public void before(){ count=1; } @Test public void test1(){ count++; assertEquals(2, count); } @Test public void test2(){ count++; assertEquals(2, count); } } EXPECTED BEHAVIOUR test1 - success test2 - fail(as expected that count will become 3) ACTUAL BEHAVIOUR test1 - success test2 - success Why junit is reinitializing class/variable with each test method invocation. It is a bug in junit or is provided intentionally.

I am trying to build a simple Java project with Maven. In my pom-file I declare JUnit 4.8.2 as the only dependency. Still Maven insists on using JUnit version 3.8.1. How do I fix it? The problem manifests itself in a compilation failure: "package org.junit does not exist". This is because of the import statement in my source code. The correct package name in JUnit 4.* is org.junit.* while in version 3.* it is junit.framework.* I think I have found documentation on the root of the problem on http://maven.apache.org/plugins/maven-surefire-plugin/examples/junit.html but the advice there seems to
