[miroslavpojer]

Background

In the design of test suites, there can be a useful ability to design common logic

• before all suites and test will be started. Similar to after alternative.
• before each test inside the suite for each test. Similar to after alternative.

Feature

• Introduce logic for BeforeAll - logic will be started before all other logic
• Introduce logic for AfterAll - logic will be started before all other logic
• Introduce logic for BeforeEachTest - logic will be started before each test inside Suite where defined.
• Introduce logic for AfterEachTest - logic will be started after each test inside Suite where defined.

Update:

• Rename existing Before and After logic to BeforeSuite and AfterSuite to better fit.
