The most common output format for RSpec test results is progress which shows
the dot (.
) or F
for each test pass and fail. RSpec supports other formats,
including JSON.
You'd typically want to use the JSON format when you want to programmatically work with the results. And the results would be most accessible if they ended up in a file.
So, when formatting the results to JSON, we typically also want to specify an
output file. We'll need to use two flags — --format
and --out
.
$ rspec --format json --out test_run_1.json
When this test run completes, we will have the results in JSON format in the
newly created test_run_1.json
file in the current directory.
See rspec --help
for more details.
