Review comment:
So, the right way to do this would be to create a test fixture:
```c++
class S3OptionsTest : public ::testing::Test {
public:
void SetUp() {
ASSERT_OK(SetEnvVar("AWS_EC2_METADATA_DISABLED", "true"));
}
void TearDown() {
ASSERT_OK(DelEnvVar("AWS_EC2_METADATA_DISABLED"));
}
};
```
And then to replace every `TEST(S3Options, ...)` with `TEST_F(S3OptionsTest,
...)`.
