There are two other unrelated failures in this test. For some reason child1 has
a space after it, thus 2 spaces before the glob, otherwise the glob is ignored
and removed.
test-run-tests and test-hghave call run-tests;
if you don't have a working build environment, and you are trying
to use --pure, then if they don't use --pure or --with-hg,
they'll break.
I want to add tests for our packaging rules, but those necessarily run
a whole build, or possibly two if both native packaging and docker are
available. This lets us flag such tests with a `#require slow` so that
they don't unnecessarily slow down normal test runs.
Before this patch, `RUNTESTDIR` is added to `PATH`, but `TESTDIR`
isn't.
This doesn't cause any problems, if `run-tests.py` runs in `tests`
directory of Mercurial source tree. In this case, `RUNTESTDIR` should
be equal to `TESTDIR`.
On the other hand, if `run-tests.py` runs in `tests` of third party
tools, commands in that directory should be executed with explicit
`$TESTDIR/` prefix in `*.t` test scripts. This isn't suitable for the
policy "drop explicit $TESTDIR from executables" of Mercurial itself
(see fcb1c7d8c36e).
BTW, fcb1c7d8c36e describes that "$TESTDIR is added to the path" even
though `TESTDIR` isn't added to `PATH` exactly speaking, because
`TESTDIR` and `RUNTESTDIR` weren't yet distinguished from each other
at that time.
This is a one of preparations for issue4677.
Before this patch, there is no way to refer files under `tests` or so
of Mercurial source tree, when `run-tests.py` runs in `tests` of third
party tools. In this case, `TESTDIR` refers the latter `tests`.
This prevents third party tools from using useful tools in Mercurial
source tree (e.g. `contrib/check-code.py`).
This patch adds `RUNTESTDIR` environment variable to refer `tests` of
Mercurial source tree, in which `run-tests.py` now running is
placed. For example, tests of third party tools can refer
`contrib/check-code.py` in Mercurial source tree as
`$RUNTESTDIR/../contrib/check-code.py`.
BTW, for similarity with `TESTDIR` referring `test*s*` directory,
newly added environment variable isn't named as `RUNTEST*S*DIR`. In
addition to it, the corresponded local variable is also named as
`runtestdir`.
This is a one of preparations for issue4677.
Before this patch, `run-tests.py` executes `hghave` by the path
relative to `TESTDIR` (= cwd of `run-tests.py` running).
This prevents third party tools for Mercurial from running
`run-tests.py`, which is placed in `tests` of Mercurial source tree,
in `tests` of own source tree. In such cases, `TESTDIR` refers the
latter `tests`, and `hghave` doesn't exist in it.
This is a one of preparations for issue4677.
$TESTDIR is added to the path, so this is superfluous. Also,
inconsistent use of quotes means we might have broken on tests with
paths containing spaces.
When the test engine fails to match output on a line marked with (?),
it will simply continue to the next expected line and try again. This
allows simplifying tests that have either version-specific or
non-fixed behavior, for instance:
$ coin-flip
heads (?)
tails (?)
(There's no form of back-tracking attempted, so optional matches
should be specific.)
This is useful information to understand what is taking time in tests. Both are
included because I can see myself sorting this output using shell script. Having
both data makes it much easier than extracting 'start'+'real'.
We currently have information about how long each test took, but we have no data
about their actual scheduling. So we now track when a test started and stopped
(in the referential of the whole tests run) to expose this information.
The data is currently in the json only because the json output is meant to be
extensible. Later changeset will includes this data in the text output and we
will be happy to bikeshed its formating there.
Yes, "end" is actually just "start" + "time", but computing it an including it
in the output is simple, cheap and convenient.
As part of writing another test, I triggered an array index error in
glob match processing code by having a (glob) line end in a single
backslash (which is the escape character).
Adding a simple bounds check prevents the error in run-tests.py.
The test runner has the ability to stop on first error.
Tests are executed in new Python threads. The test runner starts new
threads when it has capacity to do so. Before this patch, the "stop on
first error" logic would return immediately from the "run tests"
function, without waiting on test threads to complete. There was thus
a race between the test runner thread doing cleanup work and the test
thread performing activity. For example, the test thread could be in
the middle of executing a test shell script and the test runner
could remove the test's temporary directory. Depending on timing, this
could result in any number of output from the test runner.
This patch eliminates the race condition by having the test runner
explicitly wait for test threads to complete before continuing.
I discovered this issue as I modified the test harness in a subsequent
patch and was reliably able to tickle the race condition.
The xunit writer was passing a str to a minidom API. An implicit
.decode('ascii') was performed somewhere, causing UnicodeDecodeError
if test output contained non-ascii sequences.
This patch converts test output to utf-8 before passing it to minidom.
We use the "replace" strategy to ensure invalid utf-8 sequences get
munged into �.
Before this patch, "test-run-tests.t" doesn't test "run-tests.py" with
"--pure", even if outer "run-tests.py" is executed with it.
This patch uses not "HG_RUN_TESTS_PURE" but "HGTEST_RUN_TESTS_PURE",
because "HG_" prefixed environments are forcibly dropped in "_getenv()".
This is also useful to run "run-tests.py" successfully by
"run-tests.py --pure" on Windows without any compilation tools (like
VisualStudio).
Avoid spending too much time adding (glob) after running run-tests -i. This
doesn't handle all cases but it helps.
The run-tests tests add a bit of escaping of trailing (glob) in the output to
avoid interference from the outer test runner.
The regexp for matching the output lines contains a group for making multiline
substitute in a way that works with Python before 2.7.
test-largefiles-update.t, test-subrepo.t, test-tag.t, and
test-rename-dir-merge.t still warn about no result returned because of
unnecessary globs that test-check-code-hg.t wants, relating to output for
pushing to, pulling from and moving X to Y.
simplejson produces slightly different output from the built-in json
module, specifically:
* It uses 0.000 instead of 0.0000
* It likes to put a trailing space after a comma
This change works around both of those variations.
Without this change, --first causes currently-running tests to explode
in violent and surprising ways when their temporary directory gets
cleaned up. Now we just suppress failure messages from non-first
failures when running in --first mode.
This patch adds up a 'cuser' and 'csys'(cputime) info in report.json file
which generated when --json is enabled while testing.
Now the new format of report.json file is as below.
testreport ={
"test-success.t": {
"csys": "1.041",
"cuser": "1.041",
"result": "success",
"time": "2.041"
}
"test-failure.t": {
"csys": "1.041",
"cuser": "1.041",
"result": "failure",
"time": "4.430"
}
"test-skip.t": {
"csys": "1.041",
"cuser": "1.041",
"result": "skip",
"time": "3.754"
}
}
This patch added a new functionality '--json'. While testing, if '--json'
is enabled then test result data gets stored in newly created "report.json"
file in the following format.
testreport ={
"test-success.t": {
"result": "success",
"time": "2.041"
}
"test-failure.t": {
"result": "failure",
"time": "4.430"
}
"test-skip.t": {
"result": "skip"
"time": "3.754"
}
}
Otherwise, if '--json' is enabled but json module was not installed then it
will raise an error "json module not installed".
This "report.json" file will further accessed by html/javascript file for
graph usage.
The Jenkins CI system understands xunit reports natively, so this will
be helpful for anyone that wants to use Jenkins for testing hg or
extensions that use run-tests.py for their testing.
This preserves the current behavior that excludes ignored or skipped
tests from the number of tests run, except when tests are ignored due
to the --retest flag.
This adds a fair amount of overall instability in the enclosing .t. As
such, this is performed in its own commit, and a test for --keyword on
run-tests.t will be added in a followup change.
As our tests execute in child processes, this patch uses os.times()
module in replace of time.time() module to provide additional info like
user time and system time spent by child's processes along with real elapsed
time taken by a process.
There is one limitation of this patch. It can work only for Linux users and
not for Windows.
"os.times" module returns a 5-tuple of a floaing point numbers.
1) User time
2) System time
3) Child's user time
4) Child's system time
5) Ellapsed real time
On Windows, only the first two items are filled, the others are zero.
Therefore, below test cases does not break on Windows but instead gives the
zero value.
Otherwise diff may get separated from the corresponding prompt by
other threads. This required moving the interactive prompting from one
helper method to another.
