Repeat tests until it passes once, temporary solution to flaky tests

[s-dakshin]

Goal: I am trying to solve flakiness in UI tests in our custom test framework using Google Test. Such that I can re-run tests until they pass at least once. Like have them repeat 3 times and if they pass even once, mark the test as passed. The opposite of this is possible with the ::testing::GTEST_FLAG(repeat) = 3;

What I am trying to achieve is based on a blog post - https://testing.googleblog.com/2016/05/flaky-tests-at-google-and-how-we.html. Where the suggestions to flaky tests are -

1. ability to re-run only failing tests
2. an option to re-run tests automatically when they fail
3. denote a test as flaky - causing it to report a failure only if it fails 3 times in a row

Based on this, it seems like what I am trying to achieve should be possible. But based on the things I tried, here are my findings -

1. testing::FLAGS_gtest_repeat - seems to be used to run tests until it fails to help with debugging. I almost want the inverse of this.
2. testing::TestPartResult - seems to have a way to find if fatal or non-fatal errors occurred in your test. But there is no way to clear these flags or handle it inside our code. More precisely, ::testing::Test::HasFailure() is set to failure even if a test fails once, I want something like testing::TestResult::ClearTestPartResults(), but that is a private function.

Can someone please help/suggest a way to achieve my goal using existing functions/flags that Google Test framework offers?
