Example 2 with IRuntime

use of org.jacoco.core.runtime.IRuntime in project jacoco by jacoco.

the class PreMain method premain.

/**
 * This method is called by the JVM to initialize Java agents.
 *
 * @param options
 *            agent options

Example 3 with IRuntime

use of org.jacoco.core.runtime.IRuntime in project jacoco by jacoco.

the class CoreTutorial method execute.

/**
 * Run this example.
 *
 * @throws Exception
 *             in case of errors
 */
public void execute() throws Exception {

    // Now we're ready to run our instrumented class and need to startup the
    // runtime first:

    // In this tutorial we use a special class loader to directly load the
    // instrumented class definition from a byte[] instances.

    // At the end of test execution we collect execution data and shutdown
    // the runtime:
