How To Install googletest on Ubuntu 22.04
Introduction
In this tutorial we learn how to install googletest on Ubuntu 22.04.
What is googletest
googletest is:
This package provides sources for Google Test and Google Mock.
Google Test is a framework for writing C++ tests on a variety of platforms. Based on the xUnit architecture. Supports automatic test discovery, a rich set of assertions, user-defined assertions, death tests, fatal and non-fatal failures, value- and type-parameterized tests, various options for running the tests, and XML test report generation.
Google Mock is an extension of Google Test for C++ mocking. Inspired by jMock, EasyMock, and Hamcrest, and designed with C++’s specifics in mind, it can help you derive better designs of your system and write better tests.
Google Mock:
- provides a declarative syntax for defining mocks,
- can easily define partial (hybrid) mocks, which are a cross of real and mock objects,
- handles functions of arbitrary types and overloaded functions,
- comes with a rich set of matchers for validating function arguments,
- uses an intuitive syntax for controlling the behavior of a mock,
- does automatic verification of expectations (no record-and-replay needed),
- allows arbitrary (partial) ordering constraints on function calls to be expressed,
- lets a user extend it by defining new matchers and actions.
- does not use exceptions, and
- is easy to learn and use.
NOTE: This package does not contain a library to link against, but rather the source code to build the google test and mock libraries. This enables building the google test and mock libraries with the same flags as the C++ code under test.
