A failing setup step called Shell.fail, which panicked. Tests run as
parallel subtests, so that panic aborted the entire test binary: one bad
fixture cost us the results of all ~500 tests, and the failure was
reported as a stack trace rather than against the test that caused it.
Keep panicking to skip the remaining setup steps -- they would only
produce follow-on failures -- but recover in createFixture and return the
message as that test's error. All three clients already propagate an
error from a test, so they report it the way they report any other
failure.
To spot slow or anomalous tests across CI runs, record each test's run
duration when LAZYGIT_TEST_TIMING is set (to a file path);
run_integration_tests.sh prints them at the end, sorted by slowest
first. CI sets it for all integration jobs.
The harness appends to a file rather than writing to stdout/stderr
because `go test` captures those and only surfaces them with -v, which
would drown the signal in every test's verbose logs.

When a user opens a repo from the recent-repos menu or jumps between
worktrees inside lazygit, only the env vars present at process startup
reach subprocesses. That breaks pre-commit hooks and other tools whose
dependencies are pulled in by a per-repo .envrc — users were left with
read-only operations because the env their shell would normally load via
direnv never made it into lazygit's git invocations.
Shell out to `direnv export json` after each chdir and apply the JSON
delta via os.Setenv/Unsetenv. direnv tracks the previous load in its own
DIRENV_DIFF env var, so the delta also unloads vars from the old repo
when entering one without a matching .envrc. If direnv isn't on PATH the
call is a no-op, so users who don't use direnv pay nothing and users who
do need no config to opt in. Any stderr direnv emits (loading messages,
"blocked .envrc" errors, etc.) goes to the command log.
The integration test puts a fake direnv on PATH and asserts that a value
it exports reaches a custom command after switching repos. Wiring this
up needed runner.go to support `{{actualPath}}` placeholders in
ExtraEnvVars, mirroring the existing support for ExtraCmdArgs, so the
test can prepend a fixture-relative directory to PATH.

In go 1.22, loop variables are redeclared with each iteration of the
loop, rather than simple updated on each iteration. This means that we
no longer need to manually redeclare variables when they're closed over
by a function.
This changes GetRepoPaths() to pull information from `git rev-parse`
instead of effectively reimplementing git's logic for pathfinding. This
change fixes issues with bare repos, esp. versioned homedir use cases,
by aligning lazygit's path handling to what git itself does.
This change also enables lazygit to run from arbitrary subdirectories of
a repository, including correct handling of symlinks, including "deep"
symlinks into a repo, worktree, a repo's submodules, etc.
Integration tests are now resilient against unintended side effects from
the host's environment variables. Of necessity, $PATH and $TERM are the
only env vars allowed through now.
We need to fetch our list of tests both outside of our test binary and within. We need
to get the list from within so that we can run the code that drives the test and runs
assertions. To get the list of tests we need to know where the root of the lazygit repo
is, given that the tests live in files under that root.
So far, we've used this GetLazyRootDirectory() function for that, but it assumes that
we're not in a test directory (it just looks for the first .git dir it can find). Because
we didn't want to properly fix this before, we've been setting the working directory of
the test command to the lazygit root, and using the --path CLI arg to override it when
the test itself ran. This was a terrible hack.
Now, we're passing the lazygit root directory as an env var to the integration test, so
that we can set the working directory to the actual path of the test repo; removing the
need to use the --path arg.
This PR captures the code coverage from our unit and integration tests. At the
moment it simply pushes the result to Codacy, a platform that assists with
improving code health. Right now the focus is just getting visibility but I want
to experiment with alerts on PRs when a PR causes a drop in code coverage.
To be clear: I'm not a dogmatist about this: I have no aspirations to get to
100% code coverage, and I don't consider lines-of-code-covered to be a perfect
metric, but it is a pretty good heuristic for how extensive your tests are.
The good news is that our coverage is actually pretty good which was a surprise
to me!
As a conflict of interest statement: I'm in Codacy's 'Pioneers' program which
provides funding and mentorship, and part of the arrangement is to use Codacy's
tooling on lazygit. This is something I'd have been happy to explore even
without being part of the program, and just like with any other static analysis
tool, we can tweak it to fit our use case and values.
## How we're capturing code coverage
This deserves its own section. Basically when you build the lazygit binary you
can specify that you want the binary to capture coverage information when it
runs. Then, if you run the binary with a GOCOVERDIR env var, it will write
coverage information to that directory before exiting.
It's a similar story with unit tests except with those you just specify the
directory inline via `-test.gocoverdir`.
We run both unit tests and integration tests separately in CI, _and_ we run them
parallel with different OS's and git versions. So I've got each step uploading
the coverage files as an artefact, and then in a separate step we combine all
the artefacts together and generate a combined coverage file, which we then
upload to codacy (but in future we can do other things with it like warn in a PR
if code coverage decreases too much).
Another caveat is that when running integration tests, not only do we want to
obtain code coverage from code executed by the test binary, we also want to
obtain code coverage from code executed by the test runner. Otherwise, for each
integration test you add, the setup code (which is run by the test runner, not
the test binary) will be considered un-covered and for a large setup step it may
appear that your PR _decreases_ coverage on net. Go doesn't easily let you
exclude directories from coverage reports so it's better to just track the
coverage from both the runner and the binary.
The binary expects a GOCOVERDIR env var but the test runner expects a
test.gocoverdir positional arg and if you pass the positional arg it will
internally overwrite GOCOVERDIR to some random temp directory and if you then
pass that to the test binary, it doesn't seem to actually write to it by the
time the test finishes. So to get around that we're using LAZYGIT_GOCOVERDIR and
then within the test runner we're mapping that to GOCOVERDIR before running the
test binary. So they both end up writing to the same directory. Coverage data
files are named to avoid conflicts, including something unique to the process,
so we don't need to worry about name collisions between the test runner and the
test binary's coverage files. We then merge the files together purely for the
sake of having fewer artefacts to upload.
## Misc
Initially I was able to have all the instances of '/tmp/code_coverage' confined
to the ci.yml which was good because it was all in one place but now it's spread
across ci.yml and scripts/run_integration_tests.sh and I don't feel great about
that but can't think of a way to make it cleaner.
I believe there's a use case for running scripts/run_integration_tests.sh
outside of CI (so that you can run tests against older git versions locally) so
I've made it that unless you pass the LAZYGIT_GOCOVERDIR env var to that script,
it skips all the code coverage stuff.
On a separate note: it seems that Go's coverage report is based on percentage of
statements executed, whereas codacy cares more about lines of code executed, so
codacy reports a higher percentage (e.g. 82%) than Go's own coverage report
(74%).
For the "cli" and "tui" modes of the test runner there's a "-race" parameter to
turn it on; for running tests on CI with go test, you turn it on by setting the
environment variable LAZYGIT_RACE_DETECTOR to a non-empty value.
This prevents commands like "go test ./..." from looking into it, and it
prevents VS Code's Problems panel from showing errors about the go files in that
folder.
For older git versions we won't be able to support any other main branch than
"master", so hard-code that in Init.
This doesn't fix anything for older versions yet; see the next commit for that.
I don't know why we were setting the initial context to CurrentSideContext
and not just CurrentContext in the first place. If there is no current context
in either case it'll default to the files context. So the only issue is if
we anticipated that some random context would be focused and we didn't want to
activate that. But I can't think of any situation where that would happen.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
A global ~/.gitconfig file can have influence on how integration tests behave;
in my case, I had the option "merge.conflictStyle" set to "diff3", which made
the integration test "cherry_pick_conflict" fail because the diff was different
from what the test expected.
Make this more robust by telling git to ignore the global config file when
running tests.
