Design

A Testify assertion service bundle is a packaged section of code that implements the BundleActivator and Assertion Interfaces. Any unit testing is contained within this source code. Generally, the source code will consist of one java class (that runs the specific assertion), a set of unit tests, and a pom file.

Assertion Interface

The assertion interface provides one method shown below. It takes in a String of assertion information (if provided) and a processor response. It sends an AssertionStatus Object back to the engine. The assertionInfo String can be provided by the user as part of the test file. It is listed after the assertion name separated by "::".

Assertion

public AssertionStatus evaluateAssertion(String assertionInfo, Response response)

BundleActivator Interface

The bundle activator interface provides two methods, start and stop. These methods are run when the bundle is started or stopped by the engine. The stop method can be left blank. The start method is used to register the assertion service so that it can be called by the Assertion Handler. Below is the code needed to implement these methods and register the service. Replace {ASSERTION_CLASS_NAME} with the name of the class followed by "()".

BundleActivator

@Override
public void start(BundleContext bundleContext) throws Exception {

	//Register the Assertion service
	bundleContext.registerService(Assertion.class.getName(), new {ASSERTION_CLASS_NAME}, null);

}
 
@Override
public void stop(BundleContext bundleContext) throws Exception {
}

POM File

Below is a POM file template for a Testify assertion. The variables in "[ ]" will change depending on the specific assertion, the creator's organization, and the version of Testify core. Additional dependencies may be needed depending on the assertion. Also, under the maven-bundle-plugin, package exports, embedded dependencies, additional package imports, and other properties may be needed depending on the assertion.
