Strange output

[robert-andrzejuk]

The below code generates strange output. Multiple times the Failed tests are listed in an incremental manner. I would expect each check to be listed once.

Code:

#define BOOST_UT_DISABLE_MODULE
#include "ut.hpp"

#define EXPECT_THAT(expr) expect(that % expr) << "\"" #expr "\"\n"

int main() {
    using namespace boost::ut;
    using namespace boost::ut::literals;

    "basic"_test = [] {
        int a1 = 1, a2 = 1, a3 = 1, a4 = 1, a5 = 1, a6 = 1;
        int b1 = 0, b2 = 0, b3 = 0, b4 = 0, b5 = 0, b6 = 0;

        EXPECT_THAT(a1 == b1);
        EXPECT_THAT(a2 == b2);
        EXPECT_THAT(a3 == b3);
        EXPECT_THAT(a4 == b4) << fatal;
        EXPECT_THAT(a5 == b5);
        EXPECT_THAT(a6 == b6);
    };
}

Output:

I'm not sure what the interaction issue is here but maybe that it's == instead of % you'd need in the macro -- regardless you should be able to write this without the macro and get decent location information anyway.

    expect(a1 == b1);
    expect(fatal(a4 == b4)) << "fatal errror a4 not equal b4";

same problem

int main(int argc, char *argv[])
{
    ...
    cfg<override> = {.tag = {connected ? "connected" : "skip"}};
    tag("connected") / "integrational"_test = []() {
        should("eval") = []{
            sync_tnt_request([](tnt::connection &cn)  // functor to be called from another thread
            {
                ...
                // set callback to be called from main thread
                set_handler(cn.last_request_id(), [](const mp_map_reader &header, const mp_map_reader &body) {
                    // violation prints multiple times:
                    expect(ut::nothrow([&](){ throw_if_error(header, body); }));   //  <- tests.cpp:207
                    ...
                });
            });
            ...
        };
    };

    return EXIT_SUCCESS;
}

Breakpoint on error print line (within throw_if_error()) only triggers once but the output is:

$ ./cpp2tnt_tests

Minimal repro on Godbolt.

To reproduce locally:

cat - >demo.cpp <<'EOF'
#include <boost/ut.hpp>
int main() {
    using namespace boost::ut;
    "demo"_test = [] {
        expect(1 == 2);
        expect(1 == 3);
    };
}
EOF
g++ -std=c++23 -I/path/to/boost-ext-ut/include demo.cpp -o demo
./demo

Result:

Running test "demo"... FAILED
in: demo.cpp:5 - test condition:  [false]


Running test "demo"... FAILED
in: demo.cpp:5 - test condition:  [false]FAILED
in: demo.cpp:6 - test condition:  [false]

Note how even the final test counter is bugged (2 out of 1 tests failed).

Expected:

in: demo.cpp:6 - test condition:  [false]
