Add quieter EXPECT

[ninnghazad]

It'd be nice to have an EXPECT that does not print evaluated statements in stdout when -p is used. when i EXPECT compare two pieces of binary data and use -p, it prints them to stdout and messes up the terminal. would also be nice for comparing rather long strings and such - i wanna see the output from -p, but not the actual values in every case.

Can you provide examples of such current and desired outputs?

while testing a rle-compressor and xor-thingy used for some delta-compression in a thing, comparing bytestrings returned from those functions in a loop:

src/tests/test_003_util.cpp:102: passed: rle [rle,strxor] : r==b for "�A5��E�d�Er��CATy" == "�A5��E�d�Er��CATy"

All 1 selected test passed.
$ 1;2c1;2c1;2c1;2c

also note uncalled for '1;2c' s on the commandline. the full test also beeps a lot because some bytes the terminal sees as bell codes. what i would much prefer to see:

src/tests/test_003_util.cpp:102: passed: rle [rle,strxor] : r==b
...
src/tests/test_003_util.cpp:102: passed: rle [rle,strxor] : r==b
All 1 selected test passed.
$

the code for something like that looks like this:

{
        bytes a = "000000000";
        bytes b = "000001000";
        bytes r = sxor(a,rle_decompress(rle_compress(sxor(a,b))));
        EXPECT(r==b);
}

@ninnghazad , Btw, what is your use for --pass reports (w/o the expansions)?

[martinmoene]

Plan:

• [x] Handle printing of unprintable characters in strings.
  • [x] lest.hpp
  • [x] lest_cpp03.hpp
• [x] Add option to suppress "for expansion" when reporting passing tests.
  • [x] lest.hpp
  • [x] lest_cpp03.hpp

Option names could be

• --pass-zen, -z
• --pass-less, s
• --pass-no-expand, -x

@martinmoene thanks! that already is nicer - especially for cases where i want to see string output, but a failed case might produce some nasty strings. no more bell escapes already. i use --pass when writing new tests - checking if all tests are properly executed and if (except for machine-readable stuff) the used values are what i wanted. and then i use it when manually compiling - for satisfaction. just nice to write a few new bits and bobs and have all the green "passed" messages scroll by. in most cases the expansion of the condition is nice, just these cases where i test non-printable strings and those where i compare big strings.

Thanks, I'm off for a couple of days, so next actions will have to wait a little.

[ninnghazad]

thank you very much @martinmoene . i'm good with the lastest changes, and consider this solved.
