Provide a way to execute a test method for a test case or all the generated test cases

[dakusui]

From an IDE such as IntelliJ, you cannot run a test method individually. This makes quite painful to implement test code with JCUnit when we have multiple test methods in a test class and some of (or all of) them are time consuming. A user needs to modify (give @ignore annotation or comment out) their test codes to suppress the other methods than the one he/she is working on at the time.

Although this is an IntelliJ side's issue, I believe, we should have some way to workaround it.

We should be able to do it by following code.

  new JUnit4Runner.Builder(QuadraticEquationExample.class)
    .testCase(1)
    .methodName("performScenario2")
    .build()
  .run();

JUnit4Runner is found in package com.github.dakusui.jcunit8.runners.junit4.
