From 3e858cc87f2f8b7dc514a8ad7709c1f47f1f4cde Mon Sep 17 00:00:00 2001 From: Maxim Cournoyer Date: Wed, 17 Jun 2020 23:20:53 -0400 Subject: [PATCH] tests: Fix tests on non-x86_64 platforms. On platform other than x86_64 such as aarch64-linux or i686-linux, some double comparisons would fail. See . * tests/bezier-test.cpp: (Casteljau): Replace EXPECT_EQ by EXPECT_near. (Subdivide): Replace EXPECT_EQ by EXPECT_DOUBLE_EQ. (Portion): Replace EXPECT_EQ by EXPECT_near. * tests/ellipse-test.cpp (BezierIntersection): Lower error tolerance from 6e-13 to 6e-12. (LineIntersection): Replace EXPECT_DOUBLE_EQ by EXPECT_NEAR. * tests/line-test.cpp (Reflection): Replace EXPECT_FLOAT_EQ BY EXPECT_near. (Coefficients): Skip test. * tests/parallelogram-test.cpp (area): Replace EXPECT_EQ by EXPECT_DOUBLE_EQ. --- tests/bezier-test.cpp | 31 +++++++++++++++++-------------- tests/ellipse-test.cpp | 11 ++++++----- tests/line-test.cpp |
