* This requires moving Fatal_error and Loc_error to Stdune.Exn as well * Clflags.workspace_root can no longer be used in Path.to_absolute_filename. We just take a parameter instead for now. |

README.md
This file describe how the jbuilder test suite is organized.
Unit testing
The unit-tests directory contains unit tests, written in expectation
style. The test logic is implemented in unit-tests/expect_test.mll
and the various tests are in .mlt files.
The way they work is quite simple; each .mlt file is a succession of
toplevel phrases followed by the output reported by the OCaml toplevel
enclosed in an [%%expect] extension point. For instance:
6 * 7;;
[%%expect{|
- : int = 42
|}]
Blackbox testing
The blackbox-tests contains blackbox tests. I.e. we are testing the
fully built jbuilder executable on various example projects.
The tests are written in cram style. The
logic is implemented in blackbox-tests/cram.mll. It only implements
a minimal subset of cram testing. In particular the shell environment
is currently not preserved between commands, so you cannot define a
variable and use it.
Test cases are in blackbox-tests/test-cases. Each sub-directory is a
full blown jbuilder project. Each sub-directory contains a run.t
file, which represent a few invokation of jbuilder along with the
expected output.
Here is a sample .t file:
This is a comment
$ echo 'Hello, world!'
Hello, world!
$ cat plop
cat: plop: No such file or directory
[1]
The [1] represent the exit code of the command. It is printed when it
is non-zero
