121- When you have a set of tests that are related, you can group them together by
122- creating a test suite with describe. A test suite can contain other test suites
123- and tests. All tests within a suite will inherit their options from the suite
124- unless they specifically set them.
125-
126- The beforeAll and afterAll hook options can be used to do something before and
127- after all the tests in the suite run. If you would like to set values for all
128- tests within the suite, you can create a context interface that defines all the
129- values available to the tests that are defined in the beforeAll function.

197+ ### Shorthand for focusing and ignoring tests
198+
199+ To avoid having to change your test function arguments to be able to focus or
200+ ignore tests temporarily, a shorthand has been implemented. This makes it as
201+ easy as typing ` .only ` and ` .ignore ` to focus and ignore tests.
202+
203+ - To focus a test case, replace ` it ` with ` it.only ` .
204+ - To ignore a test case, replace ` it ` with ` it.ignore ` .
205+ - To focus a test suite, replace ` describe ` with ` describe.only ` .
206+ - To ignore a test suite, replace ` describe ` with ` describe.ignore ` .
207+
208+ ### Migrating from earlier versions
209+
210+ The ` TestSuite ` class has been turned into an internal only class. To create a
211+ test suite, use the ` describe ` function instead of creating a new instance of
212+ ` TestSuite ` directly.
213+
214+ The ` test ` function has been removed. Replace ` test ` calls with calls to ` it ` .
215+
216+ The ` each ` function that was previously available has been temporarily removed
217+ to allow me to switch over to the test step api quicker. I plan on implementing
218+ this later. If you make use of the ` each ` function for generating test cases, do
219+ not upgrade beyond version 0.9.5.
