The technical principles of Atlassian testing the annotation framework in the Java class library
Introduction:
In Java development, testing is one of the important parts of ensuring software quality.Atlassian is a well -known software company that developed a test annotation framework that can help developers in the Java class library to more easily write and perform test cases.This article will introduce the technical principles of the ATLASSIAN test annotation framework in the Java class library, and provide some Java code examples.
1. Overview of the Atlassian test commentary framework
The ATLASSIAN test annotation framework is based on the expansion of the Junit framework. It provides a set of custom annotations for tagging test cases and test sets, and provides some additional functions to enhance the coverage and effects of the test.
2. Detailed technical principles
The core principle of Atlassian testing the annotation framework is to analyze and process custom annotations through the runtime annotation processor to achieve automated execution of test cases.
1. Customized annotation
The ATLASSIAN test annotation framework provides a variety of custom annotations, including@test,@before,@aFTER,@a, etc.These annotations can be used to mark information such as the execution order, front conditions, rear conditions, and neglect of test cases.
2. Comment processor
During the test run, the annotation processor scan the test class and method annotations, and perform the corresponding operation according to the definition of the annotation.The annotation processor can dynamically obtain information of class and methods through the reflection mechanism, so as to achieve automated test execution process.
3. Executive order control
Through customized annotations, developers can control the execution order of test cases.For example, using the @Before annotation can perform a specific code before each test method, and the @AFTER annotation can execute a specific code after each test method.
4. The front conditions and rear conditions
Custom annotations can also be used to mark the front conditions and rear conditions of the test method.For example, using @BefaceClass annotations can execute a segment code before all test methods in the test class, and the @AterClass annotation can execute another code after all test methods are performed.
5. Ignore the test case
By using @ignore annotations, developers can record some test cases as ignoring, so as to skip these cases during the test test.This is very useful for use cases that do not need to be executed for the time being during the development process.
3. Java code example
The following is an example that shows how to use the Atlassian test commentary framework to write a simple test class:
import com.atlassian.junit.JiraRule;
import com.atlassian.junit.rules.annotation.EnableRuleAfterTest;
import org.junit.Rule;
import org.junit.Test;
@EnableRuleAfterTest
public class MyTestClass {
@Rule
public JiraRule jiraRule = new JiraRule();
@Test
public void testMethod1() {
// Test case 1 code logic
}
@Test
public void testMethod2() {
// Test case 2 code logic
}
}
In the above example, we use @test annotations to mark the two test methods, namely TestMethod1 and TestMethod2.At the same time, we also used @Rule annotations to create a Jirarule instance to enable JIRA test rules.In addition, we also used the @EnableruleaFtertest annotation, which tells the framework to perform the rules after each test method.
in conclusion:
The Atlassian test annotation framework is a powerful tool for helping developers write and perform test cases in the Java class library.By customized annotations, annotations, processors, and execution sequential control, this framework can improve the coverage and effect of testing.Developers can use these annotations and related functions freely according to their needs, so as to conduct software testing easier.
