Google Test string comparison asserts are only designed of C style
strings containing printable text of one or more lines with a
terminating NUL character. GParted is crashing when PipeCapture is
reading the binary file names being reported by fsck.fat from a very
corrupted FAT file system. Therefore need to be able to compare and
report differences of binary data stored in C++ std::string and
Glib::ustrings. Write a specific assertion to handle this.
Now these sample tests:
TEST_F( PipeCaptureTest, BinaryStringFailure )
{
inputstr = "AAAAAAAAAAAAAAAABBBBBBBBBBBBBBBBCCCCCCCCCCCCCCCC";
capturedstr = "AAAAAAAAAAAAAAAABBBBBBBBBBbbbb";
EXPECT_BINARYSTRINGEQ( inputstr, capturedstr.raw() );
}
TEST_F( PipeCaptureTest, LeadingBinaryStringFailure )
{
inputstr = "The quick brown fox jumps over the lazy dog";
capturedstr = "The quick brown fox\n";
EXPECT_BINARYSTRINGEQ( inputstr.substr( 0, capturedstr.raw().length() ),
capturedstr.raw() );
}
report failure like this:
$ ./test_PipeCapture
