From fde70a1b26e130663cc4c02e0530d3aadc165a41 Mon Sep 17 00:00:00 2001 From: Bill Hoffman Date: Thu, 5 Mar 2015 16:51:10 -0500 Subject: ctest: Add a new --repeat-until-fail option This option tells ctest to run each test N times until the test fails or the N times have run. This is useful for finding random failing tests. --- Help/manual/ctest.1.rst | 5 ++ Source/CTest/cmCTestMultiProcessHandler.cxx | 13 +++- Source/CTest/cmCTestRunTest.cxx | 73 +++++++++++++++++++--- Source/CTest/cmCTestRunTest.h | 9 +++ Source/cmCTest.cxx | 37 +++++++++-- Source/cmCTest.h | 12 +++- Source/ctest.cxx | 2 + Tests/RunCMake/CMakeLists.txt | 1 + Tests/RunCMake/CTestCommandLine/CMakeLists.txt | 3 + Tests/RunCMake/CTestCommandLine/RunCMakeTest.cmake | 25 ++++++++ Tests/RunCMake/CTestCommandLine/init.cmake | 3 + .../repeat-until-fail-bad1-result.txt | 1 + .../repeat-until-fail-bad1-stderr.txt | 1 + .../repeat-until-fail-bad2-result.txt | 1 + .../repeat-until-fail-bad2-stderr.txt | 1 + .../CTestCommandLine/repeat-until-fail-cmake.cmake | 15 +++++ .../repeat-until-fail-ctest-result.txt | 1 + .../repeat-until-fail-ctest-stderr.txt | 1 + .../repeat-until-fail-ctest-stdout.txt | 30 +++++++++ .../repeat-until-fail-good-stderr.txt | 1 + Tests/RunCMake/CTestCommandLine/test1.cmake | 13 ++++ 21 files changed, 233 insertions(+), 15 deletions(-) create mode 100644 Tests/RunCMake/CTestCommandLine/CMakeLists.txt create mode 100644 Tests/RunCMake/CTestCommandLine/RunCMakeTest.cmake create mode 100644 Tests/RunCMake/CTestCommandLine/init.cmake create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-bad1-result.txt create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-bad1-stderr.txt create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-bad2-result.txt create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-bad2-stderr.txt create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-cmake.cmake create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-ctest-result.txt create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-ctest-stderr.txt create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-ctest-stdout.txt create mode 100644 Tests/RunCMake/CTestCommandLine/repeat-until-fail-good-stderr.txt create mode 100644 Tests/RunCMake/CTestCommandLine/test1.cmake diff --git a/Help/manual/ctest.1.rst b/Help/manual/ctest.1.rst index cc132c2..dd3bcfb 100644 --- a/Help/manual/ctest.1.rst +++ b/Help/manual/ctest.1.rst @@ -194,6 +194,11 @@ Options subsequent calls to ctest with the --rerun-failed option will run the set of tests that most recently failed (if any). +``--repeat-until-fail `` + Require each test to run ```` times without failing in order to pass. + + This is useful in finding sporadic failures in test cases. + ``--max-width `` Set the max width for a test name to output diff --git a/Source/CTest/cmCTestMultiProcessHandler.cxx b/Source/CTest/cmCTestMultiProcessHandler.cxx index eb33d8e..bd090db 100644 --- a/Source/CTest/cmCTestMultiProcessHandler.cxx +++ b/Source/CTest/cmCTestMultiProcessHandler.cxx @@ -121,6 +121,11 @@ void cmCTestMultiProcessHandler::StartTestProcess(int test) this->RunningCount += GetProcessorsUsed(test);
