Run multiple google test files and collect statistics

Google Test Runner

Intro

It is a simple tools to run many googletest suits (separate executables) and collect overall statistics.

Why

C++ googletest is great lib to test C++ code. But I run into a problem how to run many googletest executables locally and collect an overall statistics. Lets say tests are fast, but initialization for a suite takes some time. For exammple I have 20 test case suits. Initialization (::testing::Test::SetUpTestCase) for each suit takes about 1 sec. And I have about 500 test.

Ctest -j4 does the thing. But it runs every test separatelly, invokes ::testing::Test::SetUpTestCase for each test. It ends up to 500 sec/4 (number of processes) = 125 sec.

I can run all tests using find . -type f -name '*_test' -exec bash -c {} ';'. But it does not show failures at the end.

Installation

Before: You must have go >= 1.12 installed.

1. Clone the repo git clone https://github.com/airenas/google-test-runner

2. Build cd google-test-runner/cmd/google-test-runner && go build

3. Copy executable somewhere on your path sudo cp google-test-runner /usr/local/bin

Usage

Run google-test-runner -h for a help.

1. Go to a dir containing googletest executables inside

2. Lets say find . -type f -name '*_test' - returns googletests with relative paths

3. Invoke the tests:

• Standard: find . -type f -name '*_test' | google-test-runner
• Filter as parameter: google-test-runner -f ./**/*_test
• Show only failing tests: google-test-runner -o f -f ./**/*_test
• One worker: google-test-runner -j 1 -s -f ./**/*_test
