A designed fail test is unexpectedly passed

[sytuannguyen]

I have tried to make a test expectedly fail but it is passed by the build.
Precisely, I have changed the line 132 in the test testElasticIsotropic.cpp to make it fail as follow

Initial code

EXPECT_DOUBLE_EQ( stress( 0, 0, 5 ), 0 );

Modified code to make it fail

EXPECT_DOUBLE_EQ( stress( 0, 0, 5 ), 1.0 );

However, I have observed that the build is successful with this change. I have verified that this test is well listed in the corresponding CMakeList.txt
