Message : Don't inherit ANGLETest SetUp and TearDown. Instead of inheriting from testing::Test's SetUp and TearDown we add new methods 'testSetUp' and 'testTearDown'. This helps prevent a common error of forgetting to call the base class method. Also add a check in the ANGLETest destructor that SetUp and TearDown have been called. Bug: angleproject:3393 Change-Id: Iab211305cc06ffea9ca649e864ddc9b180f2cba0 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1593960 Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
