patch 9.1.0681: tests: Analyzing failed screendumps is hard
Problem: tests: Analyzing failed screendumps is hard
Solution: Facilitate the viewing of rendered screendumps under src/
add some documentation on how to use the viewdumps.vim
script (Aliaksei Budavei)
With the submitted "viewdumps.vim" script, a few manual
steps in typical workflows (see below) can be automated.
The updated "README.txt" contains additional information.
============================================================
Reviewing LOCAL failed screendump tests can be arranged as
follows:
1) Run tests and generate screendumps:
------------------------------------------------------------
cd /path/to/fork/src/testdir
make
------------------------------------------------------------
2) Examine the screendumps from the "failed" directory:
------------------------------------------------------------
../vim -u NONE -S viewdumps.vim
------------------------------------------------------------
============================================================
Reviewing UPLOADED failed screendump tests can be arranged
as follows (it can be further locally scripted):
1) Fetch an artifact with failed screendumps from
"github.com/vim/vim/actions/runs/A_ID/artifacts/B_ID".
2) Extract the archived files:
------------------------------------------------------------
unzip /tmp/failed-tests.zip -d /tmp
------------------------------------------------------------
3) Set up the "dumps" directory. Create a symlink to
"/path/to/fork/dirs/dumps" in the extracted directories so
that term_dumpdiff() can be used. (The lookup algorithm
resolves "dumps" for every loaded filename. So, with
"/tmp/src/testdir/failed/*.dump" files passed as script
arguments, the algorithm will make the files in
"/tmp/src/testdir/dumps" queried.)
------------------------------------------------------------
cd /path/to/fork
ln -s $(pwd)/src/testdir/dumps /tmp/src/testdir/dumps
------------------------------------------------------------
4) Examine the extracted screendumps:
------------------------------------------------------------
./src/vim -u NONE -S src/testdir/viewdumps.vim \
/tmp/src/testdir/failed/*.dump
------------------------------------------------------------
5) Clean up:
------------------------------------------------------------
unlink /tmp/src/testdir/dumps
rm -rf /tmp/src
------------------------------------------------------------
============================================================
Reviewing SUBMITTED FOR PULL REQUEST screendump tests can be
arranged as follows (it can be further locally scripted):
1) List the fetched changeset and write the changed "dumps"
filenames to "/tmp/filelist":
------------------------------------------------------------
cd /path/to/fork
git switch prs/1234
git diff-index --relative=src/testdir/dumps/ \
--name-only prs/1234~1 > /tmp/filelist
------------------------------------------------------------
2) Reconcile relative filepaths, and copy next-to-be-updated
"dumps" files in the "failed" directory (note the missing
new screendumps, if any):
------------------------------------------------------------
git switch master
cd src/testdir/dumps
test -d ../failed || mkdir ../failed
cp -t ../failed $(cat /tmp/filelist)
------------------------------------------------------------
3) Remember about the introduced INVERTED relation between
"dumps" and "failed", i.e. the files to be committed are in
"dumps" already and their previous versions are in "failed";
therefore, copy the missing new screendumps from "dumps" to
"failed" (otherwise these won't be shown):
------------------------------------------------------------
git switch prs/1234
cp -t ../failed foo_10.dump foo_11.dump foo_12.dump
------------------------------------------------------------
4) Examine the screendumps from the "failed" directory (new
screendumps will be shown with no difference between their
versions):
------------------------------------------------------------
cd ..
../vim -u NONE -S viewdumps.vim
------------------------------------------------------------
