There are two cases that prompt this behavior: - All test cases in the binary are disabled. - There are more shards defined than test cases, so some shards are empty. The result in each case is the same: the test runner needs to spin up additional processes that do nothing, which is wasteful, especially when tests need expensive resources.

Announcements
Documentation Updates
Our documentation is now live on GitHub Pages at https://google.github.io/googletest/. We recommend browsing the documentation on GitHub Pages rather than directly in the repository.
Release 1.17.0
Release 1.17.0 is now available.
The 1.17.x branch [requires at least C++17]((https://opensource.google/documentation/policies/cplusplus-support#c_language_standard).
Continuous Integration
We use Google's internal systems for continuous integration.
Coming Soon
- We are planning to take a dependency on Abseil.
Welcome to GoogleTest, Google's C++ test framework!
This repository is a merger of the formerly separate GoogleTest and GoogleMock projects. These were so closely related that it makes sense to maintain and release them together.
Getting Started
See the GoogleTest User's Guide for documentation. We recommend starting with the GoogleTest Primer.
More information about building GoogleTest can be found at googletest/README.md.
Features
- xUnit test framework:
Googletest is based on the xUnit testing framework, a popular architecture for unit testing - Test discovery:
Googletest automatically discovers and runs your tests, eliminating the need to manually register your tests - Rich set of assertions:
Googletest provides a variety of assertions, such as equality, inequality, exceptions, and more, making it easy to test your code - User-defined assertions:
You can define your own assertions with Googletest, making it simple to write tests that are specific to your code - Death tests:
Googletest supports death tests, which verify that your code exits in a certain way, making it useful for testing error-handling code - Fatal and non-fatal failures:
You can specify whether a test failure should be treated as fatal or non-fatal with Googletest, allowing tests to continue running even if a failure occurs - Value-parameterized tests:
Googletest supports value-parameterized tests, which run multiple times with different input values, making it useful for testing functions that take different inputs - Type-parameterized tests:
Googletest also supports type-parameterized tests, which run with different data types, making it useful for testing functions that work with different data types - Various options for running tests:
Googletest provides many options for running tests including running individual tests, running tests in a specific order and running tests in parallel
Supported Platforms
GoogleTest follows Google's Foundational C++ Support Policy. See this table for a list of currently supported versions of compilers, platforms, and build tools.
Who Is Using GoogleTest?
In addition to many internal projects at Google, GoogleTest is also used by the following notable projects:
- The Chromium projects (behind the Chrome browser and Chrome OS).
- The LLVM compiler.
- Protocol Buffers, Google's data interchange format.
- The OpenCV computer vision library.
