## Changes
diff.py is like "diff -r -U2" but it applies replacements first to the
argument.
This allows comparing different output files and directories but ignore
differences that are going to be replaced by placeholders.
This is useful for tests that record large amount of files, specifically
"bundle init" with standard templates. In those tests, changing one
parameter results in a small diff so recording the full directory is not
helpful, because it's hard to see what changed there. I'm using it in
implementation of serverless mode for templates that need it: #2348 The
serverless templates are slightly different from classic, capturing the
diff helps to see exactly where.
Related small changes:
- Add [TESTROOT] replacement for absolute path to acceptance directory
in git repo.
- Add $TESTDIR env var for absolute path to a given test in git repo.
## Tests
- New test acceptance/selftest/diff to test the helper.
- Via #2348 which makes use of this feature.
## Changes
- Currently if you define [[Server]] block, you disable the default
server implementation. With this change [[Server]] block takes
precedence over default server but default server remains.
- Switched mux implementation to
[gorilla/mux](https://github.com/gorilla/mux) -- unlike built-in it does
not panic if you set two handlers on the same part (instead the earliest
one wins). It also does not have any dependencies.
- Move acceptance/selftest into acceptance/selftest/basic and added
acceptance/selftest/server that demoes server override.
- Rewrite server set up to ensure that env vars and replacements are set
up correctly. Previously replacements for DATABRICKS_HOST referred to
default server, not to the custom server.
- Avoid calling CurrentUser.Me() in the local case. This allows
overriding /api/2.0/preview/scim/v2/Me, which we use in some tests (e.g.
bundle/templates-machinery/helpers-error). Previously the test passed
because CurrentUser.Me() was calling default server which is incorrect
but it happened to make the tests pass.
- The default server is now available on DATABRICKS_DEFAULT_HOST env
var.
- Rewrite "not found" handler in local test to handle error better (do
not raise http500 when header is already written).
## Tests
New acceptance test selftest/server specifically tests that both custom
and default handlers are available in a single test.
$VARNAME is what we use for environment variables, it's good to
separate.
Some people use envsubst for homemade variable interpolation, it's also
good to have separation there.
## Changes
- Ability to extend a list of replacements via test.toml
- Modify selftest to both demo this feature and to get rid of sed on
Windows.
## Tests
Acceptance tests. I'm also using it
https://github.com/databricks/cli/pull/2213 for things like pid.
