Basic Assertions
Fatal assertion Nonfatal assertion Verifies
ASSERT_TRUE(condition); EXPECT_TRUE(condition); condition is true
ASSERT_FALSE(condition); EXPECT_FALSE(condition); condition is false
Binary Comparison
Fatal assertion Nonfatal assertion Verifies
ASSERT_EQ(val1,val2); EXPECT_EQ(val1,val2); val1 == val2
ASSERT_NE(val1,val2); EXPECT_NE(val1,val2); val1 != val2
ASSERT_LT(val1,val2); EXPECT_LT(val1,val2); val1 < val2
ASSERT_LE(val1,val2); EXPECT_LE(val1,val2); val1 <= val2
ASSERT_GT(val1,val2); EXPECT_GT(val1,val2); val1 > val2
ASSERT_GE(val1,val2); EXPECT_GE(val1,val2); val1 >= val2
String Comparison
Fatal assertion Nonfatal assertion Verifies
ASSERT_STREQ(str1,str2); EXPECT_STREQ(str1,_str_2); the two C strings have the same content
ASSERT_STRNE(str1,str2); EXPECT_STRNE(str1,str2); the two C strings have different content
ASSERT_STRCASEEQ(str1,str2); EXPECT_STRCASEEQ(str1,str2); the two C strings have the same content, ignoring case
ASSERT_STRCASENE(str1,str2); EXPECT_STRCASENE(str1,str2); the two C strings have different content, ignoring case
Floating-Point Macros
Fatal assertion Nonfatal assertion Verifies
ASSERT_FLOAT_EQ(val1, val2); EXPECT_FLOAT_EQ(val1, val2); the two float values are almost equal
ASSERT_DOUBLE_EQ(val1, val2); EXPECT_DOUBLE_EQ(val1, val2); the two double values are almost equal
ASSERT_NEAR(val1, val2, abs_error); EXPECT_NEAR(val1, val2, abs_error); the difference between val1 and val2 doesn't exceed the given absolute error
How to Write a Death Test
Fatal assertion Nonfatal assertion Verifies
ASSERT_DEATH(statement, regex); EXPECT_DEATH(statement, regex); statement crashes with the given error
ASSERT_DEATH_IF_SUPPORTED(statement, regex); EXPECT_DEATH_IF_SUPPORTED(statement, regex); if death tests are supported, verifies that statement crashes with the given error; otherwise verifies nothing
ASSERT_EXIT(statement, predicate, regex); EXPECT_EXIT(statement, predicate, regex); statement exits with the given error and its exit code matches predicate
