## Interface TestSuite

-     public interface TestSuite

  A named suite of test cases that are executed altogether. The suite suite is created with the `create(String)` and the returned suite contains initially no tests.

  The suite can declare a callback before the suite with `before(io.vertx.core.Handler)` or after the suite with `after(io.vertx.core.Handler)`.

  The suite can declare a callback before each test with `beforeEach(io.vertx.core.Handler)` or after each test with `afterEach(io.vertx.core.Handler)`.

  Each test case of the suite is declared by calling the `test(String, io.vertx.core.Handler)` method.

    All Methods Static Methods Instance Methods Abstract Methods Default Methods
    Modifier and Type | Method and Description
    --- | ---
    `TestSuite` | `after(Handler<TestContext> callback)` Set a callback executed after the tests.
    `TestSuite` | `afterEach(Handler<TestContext> callback)` Set a callback executed after each test and before the suite `after` callback.
    `TestSuite` | `before(Handler<TestContext> callback)` Set a callback executed before the tests.
    `TestSuite` | `beforeEach(Handler<TestContext> callback)` Set a callback executed before each test and after the suite `before` callback.
    `static TestSuite` | `create(Object testSuiteObject)` Create and return a new test suite configured after the `testSuiteObject` argument.
    `static TestSuite` | `create(String name)` Create and return a new test suite.
    `TestCompletion` | `run()` Run the testsuite with the default options. When the test suite is executed in a Vertx context (i.e `Vertx.currentContext()` returns a context) this context's event loop is used for running the test suite.
    `TestCompletion` | `run(TestOptions options)` Run the testsuite with the specified `options`. When the test suite is executed in a Vertx context (i.e `Vertx.currentContext()` returns a context) this context's event loop is used for running the test suite unless the `TestOptions.setUseEventLoop(Boolean)` is set to `false`.
    `TestCompletion` | `run(Vertx vertx)` Run the testsuite with the default options and the specified `vertx` instance. The test suite will be executed on the event loop provided by the `vertx` argument.
    `TestCompletion` | `run(Vertx vertx, TestOptions options)` Run the testsuite with the specified `options` and the specified `vertx` instance. The test suite will be executed on the event loop provided by the `vertx` argument when `TestOptions.setUseEventLoop(Boolean)` is not set to `false`.
    `TestSuite` | `test(String name, Handler<TestContext> testCase)` Add a new test case to the suite.

- - ### Method Detail

    - #### create

          static TestSuite create(String name)

      Create and return a new test suite.
      Parameters:
        `name` - the test suite name
      Returns:
        the created test suite

    - #### create

          static TestSuite create(Object testSuiteObject)

      Create and return a new test suite configured after the `testSuiteObject` argument. The `testSuiteObject` argument methods are inspected and the public, non static methods with `TestContext` parameter are retained and mapped to a Vertx Unit test suite via the method name:
      - `before` : `before(io.vertx.core.Handler<io.vertx.ext.unit.TestContext>)` callback
      - `after` : `after(io.vertx.core.Handler<io.vertx.ext.unit.TestContext>)` callback
      - `beforeEach` : `beforeEach(io.vertx.core.Handler<io.vertx.ext.unit.TestContext>)` callback
      - `afterEach` : `afterEach(io.vertx.core.Handler<io.vertx.ext.unit.TestContext>)` callback
      - when the name starts with `test` :`test(java.lang.String, io.vertx.core.Handler<io.vertx.ext.unit.TestContext>)` callback named after the method name
      Parameters:
        `testSuiteObject` - the test suite object
      Returns:
        the configured test suite

    - #### before

          TestSuite before(Handler<TestContext> callback)

      Set a callback executed before the tests.
      Parameters:
        `callback` - the callback
      Returns:
        a reference to this, so the API can be used fluently

    - #### beforeEach

          TestSuite beforeEach(Handler<TestContext> callback)

      Set a callback executed before each test and after the suite `before` callback.
      Parameters:
        `callback` - the callback
      Returns:
        a reference to this, so the API can be used fluently

    - #### after

          TestSuite after(Handler<TestContext> callback)

      Set a callback executed after the tests.
      Parameters:
        `callback` - the callback
      Returns:
        a reference to this, so the API can be used fluently

    - #### afterEach

          TestSuite afterEach(Handler<TestContext> callback)

      Set a callback executed after each test and before the suite `after` callback.
      Parameters:
        `callback` - the callback
      Returns:
        a reference to this, so the API can be used fluently

    - #### test

          TestSuite test(String name,
                         Handler<TestContext> testCase)

      Add a new test case to the suite.
      Parameters:
        `name` - the test case name
        `testCase` - the test case
      Returns:
        a reference to this, so the API can be used fluently

    - #### run

          TestCompletion run()

      Run the testsuite with the default options.

      When the test suite is executed in a Vertx context (i.e `Vertx.currentContext()` returns a context) this context's event loop is used for running the test suite. Otherwise it is executed in the current thread.

      The returned `Completion` object can be used to get a completion callback.
      Returns:
        the related test completion

    - #### run

          TestCompletion run(TestOptions options)

      Run the testsuite with the specified `options`.

      When the test suite is executed in a Vertx context (i.e `Vertx.currentContext()` returns a context) this context's event loop is used for running the test suite unless the `TestOptions.setUseEventLoop(Boolean)` is set to `false`. In this case it is executed by the current thread.

      Otherwise, the test suite will be executed in the current thread when `TestOptions.setUseEventLoop(Boolean)` is set to `false` or `null`. If the value is `true`, this methods throws an `IllegalStateException`.

      The returned `Completion` object can be used to get a completion callback.
      Parameters:
        `options` - the test options
      Returns:
        the related test completion

    - #### run

          TestCompletion run(Vertx vertx)

      Run the testsuite with the default options and the specified `vertx` instance.

      The test suite will be executed on the event loop provided by the `vertx` argument. The returned `Completion` object can be used to get a completion callback.

      Parameters:
        `vertx` - the vertx instance
      Returns:
        the related test completion

    - #### run

          TestCompletion run(Vertx vertx,
                             TestOptions options)

      Run the testsuite with the specified `options` and the specified `vertx` instance.

      The test suite will be executed on the event loop provided by the `vertx` argument when `TestOptions.setUseEventLoop(Boolean)` is not set to `false`. The returned `Completion` object can be used to get a completion callback.
      Parameters:
        `vertx` - the vertx instance
        `options` - the test options
      Returns:
        the related test completion
