JUNIT JUPITER (Aggregator) framework Frequently Ascension and solutions
Junit Jupiter is a Junit5 -based testing framework, providing a set of powerful and flexible tools for Java developers to write and execute unit testing.The Aggregator module of this framework is one of the core components of Junit Jupiter, which is used to aggregate multiple test classes.When using Junit Jupiter Aggregator framework, some common problems may occur. The following will introduce these problems and provide corresponding solutions and Java code examples.
1. How to gather multiple test classes in Junit Jupiter Aggregator?
You can use Junit Jupiter Aggregator's `@SuitedisplayName` annotation to aggregate multiple test classes.First, use the `@suite` annotation in the Aggregator test class to pass the test class to be aggregated as a parameter.Then, use the `@suitedisplayname` annotation as the Aggregator test class setting a display name.The following is an example:
import org.junit.platform.runner.JUnitPlatform;
import org.junit.platform.suite.api.SelectPackages;
import org.junit.platform.suite.api.Suite;
import org.junit.platform.suite.api.SuiteDisplayName;
import org.junit.runner.RunWith;
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("My Test Suite")
@Suite(@SelectPackages("com.example.tests"))
public class TestSuite {
}
In the above example, the test class `testsuite` aggregates all the test classes with the package name` com.example.tests`, and set the name of the polymerization test kit to "My Test Suite".
2. How to disable specific test or test methods in Junit Jupiter Aggregator?
You can use the `@Excludepackages` and@ExcludeClassNamePatters` annotations in the aggregator test class to disable the specific test class or test method.The two annotations can be used to eliminate test or methods that do not need to be executed according to the package name and class name mode, respectively.The following is an example:
import org.junit.platform.runner.JUnitPlatform;
import org.junit.platform.suite.api.SelectPackages;
import org.junit.platform.suite.api.Suite;
import org.junit.platform.suite.api.SuiteDisplayName;
import org.junit.runner.RunWith;
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("My Test Suite")
@Suite(
@SelectPackages(value = "com.example.tests",
excludeClassNamePatterns = ".*IntegrationTest")
)
public class TestSuite {
}
In the above example, the test class `testsuite` aggregates all the test classes named` com.example.tests`, but exclude all test classes ending with "Integrationtest".
3. How to customize the execution order of Junit Jupiter Aggregator test kit?
You can use the implementation sequence of defining test kits by using the implementation of the test kit through the implementation class of the test kit by using the ``@testMethodorDerreder` annotation and the `MethodorderDerr" interface.The following is an example:
import org.junit.platform.runner.JUnitPlatform;
import org.junit.platform.suite.api.SelectPackages;
import org.junit.platform.suite.api.Suite;
import org.junit.platform.suite.api.SuiteDisplayName;
import org.junit.runner.RunWith;
import org.junit.jupiter.api.MethodOrderer;
import org.junit.jupiter.api.TestMethodOrder;
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("My Test Suite")
@Suite(
@SelectPackages("com.example.tests")
)
@TestMethodOrder(MethodOrderer.Alphanumeric.class)
public class TestSuite {
}
In the above example, the test class `testsuite` aggregates all the test classes of the bag named` com.example.tests`, and use the `methodorderr.alphaanumeric` to implement the execution order of the test method as the number of letters.
Through the above examples, you can solve some common problems when using the Junit Jupiter Aggregator framework, and deeply understand how to write and manage the code of the polymerization test kit.I hope this article can help you perform unit testing more smoothly and efficiently when using the Junit Jupiter Aggregator framework.
