What is rule in unit testing?
They test specific functionality of a method or class that have a clear pass/fail condition. In other words, a unit test is just a method written in code. A “good” unit test follows these rules: The test only fails when a new bug is introduced into the system or requirements change.
What types of rules we can unit test in PEGA?
To unit test a rule, open the rule form and run the rule. For some rule types, such as binary file rules, Pega Platform does not provide an option for unit testing. If the rule cannot be unit tested, the Run option is not available.
What is a test rule?
A TestRule is an alteration in how a test method, or set of test methods, is run and reported. A TestRule may add additional checks that cause a test that would otherwise fail to pass, or it may perform necessary setup or cleanup for tests, or it may observe test execution to report it elsewhere.
Can a unit test be run in isolation?
A unit test should not rely on any external state, such as contents of a database table. It should purely test one unit of code in isolation.
What’s the difference between unit tests and unit tests?
Testing itself could take seconds for trivial changes, or minutes for larger changes. Lastly, this process must be repeated for every change that you make in the system. Unit tests, on the other hand, take milliseconds, can be run at the press of a button, and don’t necessarily require any knowledge of the system at large.
Can a unit test be executed in memory?
It’s generally accepted that Unit tests should be executed entirely in memory, be self-contained and be exactly repeatable. But the Timer uses the system timer so the test is not self-contained, neither is it in a constant state as the timer is busy counting down some variable.
What are the basic building blocks of unit testing?
The basic building blocks of unit testing are test cases — single scenarios that must be set up and checked for correctness. In unittest , test cases are represented by unittest.TestCase instances. To make your own test cases you must write subclasses of TestCase or use FunctionTestCase.
