How to create src/test/data/script_tests.json JSON file? #11636

Hi! I'd like to know how to create src/test/data/script_tests.json JSON file? Thanks.

The JSON file already exists, there's nothing you need to do to create it.

Do you mean how to create the header file from the JSON file? The src/Makefile.test.include has the commands.

%.json.h: %.json @$(MKDIR_P) $(@D) @{
echo "namespace json_tests{" &&
echo "static unsigned const char $(*F)[] = {" &&
$(HEXDUMP) -v -e '8/1 "0x%02x, "' -e '"\n"' $< | $(SED) -e 's/0x ,//g' &&
echo "};};";
} > "$@.new" && mv -f "$@.new" "$@" @echo "Generated $@"

Or to make it suitable for a standalone command line (you'll need to add the echos to the top and bottom if desired):

hexdump script_tests.json -v -e '8/1 "0x%02x, "' -e '"\n"' | sed -e 's/0x ,//g'

@sipsorcery Nope. I am making my own bitcoin and I'd like to switch the existing file. I've founded this code and is there an way to activate this?

bitcoin/src/test/script_tests.cpp:

// Uncomment if you want to output updated JSON tests. // #define UPDATE_JSON_TESTS

In that case you just do exactly as it says. Uncomment the define and then rebuild the bitcoin source. Once the build is complete run test_bitcoin and you should end up with a script_test.json.gen.

Attached is the file I got from master.
