1 Create a standard Maven project, remember to select <packaging>war</packaging> war or jar in Pom, but not pom, otherwise the maven test command will only build the project. This is the pit I encountered when building a test project
2 Introducing JMockit dependencies
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<!--<scope>test</scope>-->
</dependency>
<dependency>
<groupId>org.jmockit</groupId>
<artifactId>jmockit</artifactId>
<version>1.38</version>
<!--<scope>runtime</scope>-->
</dependency>
3 Introduce maven-surefire-plugin, otherwise, after the Jmockit test runs, the HTML test coverage report will not be generated
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<!-- Bind to maven test phase -->
<artifactId>maven-surefire-plugin</artifactId>
<version>2.20</version>
<configuration>
<systemPropertyVariables>
<coverage-output>html</coverage-output>
<coverage-outputDir>target/coverage-report</coverage-outputDir>
</systemPropertyVariables>
</configuration>
</plugin>
</plugins>
Special attention should be paid here. The maven test command will only run the test classes under src/test/java. The naming rules are as follows:
The test classes included by default are:
**/*Test.java
**/Test*.java
**/*TestCase .java
default excluded test classes:
**/Abstract*Test.java
**/Abstract*TestCase.java
4 For example:
@RunWith(JMockit.class)
public class TestJApp1_1 {
@Tested
Service testedService;
@Injectable
Dependency dependency;
@Test
public void exeUnitTest() {
new Expectations() {{
dependency.findSomeData(anyString);
result = new Data("345");
}};
testedService.doSomething("...");
}
}
The test class is placed under src/test/java
public class Service {
private Dependency dependency;
public Data doSomething(String someData) {
Data data = dependency.findSomeData(someData);
System.out.println(data.getText());
return data;
}
public String fun() {
return "call original method";
}
}
public class Dependency {
public Data findSomeData(String anyString) {
System.out.println("Dependency -->"+anyString);
log(anyString);
return new Data(anyString);
}
private void log(String text){
System.out.println("Dependency private log -->"+text);
}
}
public class Data {
private String text;
public Data(String text) {
this.text = text;
}
public String getText() {
return text;
}
}
This class is placed under src/main/java. Right-clicking runas or maven test will generate a test report, the effect is as follows
