SCALATESTPLUS PLAY framework in the Java class library
SCALATESTPLUS PLAY is a test framework used in the Java library, which can help developers write reliable and easy -to -maintain test cases.This guide will introduce how to use the Scientplus Play framework in the Java project and provide the necessary Java code example.
Step 1: Add scalatplus play dependence
To use the SCALATESTPLUS PLAY framework, we first need to add corresponding dependencies to the construction configuration file of the project.In the Maven project, you can add the following dependencies to the pom.xml file:
<dependency>
<groupId>org.scalatestplus.play</groupId>
<artifactId>scalatestplus-play_2.13</artifactId>
<version>5.1.0</version>
<scope>test</scope>
</dependency>
Step 2: Write test cases
Once you add dependencies, you can start writing test cases.The ScalantPlus Play framework provides some useful features and tools to help you write high -quality tests.The following is a simple example:
import org.scalatestplus.play.PlaySpec;
import play.mvc.Result;
import play.test.WithApplication;
import static play.mvc.Http.Status.OK;
import static play.test.Helpers.contentAsString;
import static play.test.Helpers.fakeRequest;
import static play.test.Helpers.route;
public class MyControllerSpec extends PlaySpec {
public class FakeApplication extends WithApplication {
public FakeApplication() {
super(play.api.test.Helpers.fakeApplication());
}
}
"MyController" should {
"return a successful response" in new FakeApplication() {
Result result = route(fakeRequest(GET, "/mycontroller")).get();
int status = result.status();
String content = contentAsString(result);
assert(status == OK);
assert(content.equals("Hello, world!"));
}
}
}
In the above example, we define a controller called MyController and write a test case to verify whether it returns a successful response.By inheriting the PlaySpec class, we can use various assertions and tools provided by the ScaladPlus Play framework to write tests.
Step 3: Run test test
Once you write the test case, you can use conventional testing operators to run these tests.In most Java integrated development environments, you can right -click the strike test class and select the "Run" option, or run a specific test class in the command line.
After running the test, you will see that the test operator performs each test case and reports the results of each test.If all the test passes, it means that your code is correct in satisfying the expected behavior.
Summarize
The ScalantPlus Play framework provides powerful tools and functions for the unit test of the PLAY framework in the Java library.By following the steps in this guide, you can easily use Scalatemstplus Play to write reliable and easy -to -maintain test cases.
