Examples with LoggerRuntime org.jacoco.core.runtime.LoggerRuntime used on opensource projects

Example 1 with LoggerRuntime

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

the class CoreTutorial method execute.

/**
 * Run this example.
 *
 * @throws Exception
 *             in case of errors
 */
public void execute() throws Exception {
    final String targetName = TestTarget.class.getName();
    // For instrumentation and runtime we need a IRuntime instance
    // to collect execution data:
    final IRuntime runtime = new LoggerRuntime();
    // The Instrumenter creates a modified version of our test target class
    // that contains additional probes for execution data recording:
    final Instrumenter instr = new Instrumenter(runtime);
    InputStream original = getTargetClass(targetName);

    // Now we're ready to run our instrumented class and need to startup the
    // runtime first:
    final RuntimeData data = new RuntimeData();

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