inline_tests Dune variable so that inline tests are dropped in release buildsRuntime.Test_result.record system by Runtime.add_evaluatorSupport literate-style .ml files that allow ocaml code interleaved with expected output annotations. Compiling with the ppx_expect_test generates a program that outputs the original source file, but with the actual output substituted for the expected-output annotations. Then we can pat-diff the original file against the output file.
Examples in the test/ and example/ folders.
Expect-tests can now be written inline in libraries by using let%expect_test.
The runtime library has been split into two components: the test runner, which collects the output of the test body, and registers enough information to construct the *.ml.corrected file from the input; and the test evaluator, which compares the test output against the expected output and generates the output files.
Ppx_core evolution.let%test_module, display the position and name of the TEST_MODULE, same as for the let%test.Mark attributes as handled inside explicitly dropped pieces of code.
So that a @@deriving inside a let%test dropped by ppx_inline_test_drop doesn't cause a failure.
