For example, a program that uses a database server is relatively slow and consumes significant system resources – which impedes testing productivity. Also, a test case might require values outside those stored in the database. A test double might provide a static value instead of accessing a database.
Pytest's markers can, in addition to altering test behaviour, also filter tests. Pytest's markers are Python decorators starting with the @pytest. mark.< markername > syntax placed on top of test functions. With different arbitrarily named markers, running pytest -m <markername> on the command line will only run those tests decorated with such ...
Unit test framework including strict and loose mocks, auto-discovering of tests, suites, BDD-ish style notation, test protected against exceptions, "natural language" output, extensible reporter, learning mocks to discover actual values sent to a mock. CHEAT: Yes: 2012 [41] BSD: Header-only unit testing framework. Multi-platform.
"We see evidence in this survey that consumers expect tariffs to raise the prices of many types of goods," said Oliver Allen, senior U.S. economist at Pantheon Macroeconomics.
Mock objects have the same interface as the real objects they mimic, allowing a client object to remain unaware of whether it is using a real object or a mock object. Many available mock object frameworks allow the programmer to specify which methods will be invoked on a mock object, in what order, what parameters will be passed to them, and what values will be returned.
In computer programming, several language mechanisms exist for exception handling. The term exception is typically used to denote a data structure storing information about an exceptional condition. One mechanism to transfer control, or raise an exception, is known as a throw; the exception is said to be thrown. Execution is transferred to a catch.

C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
