Add testing utilities for pre-generating temp filename and asserting diffs.
Review Request #11801 — Created Aug. 24, 2021 and submitted
In an effort to reduce the workload of some unit tests, and create a
more standardized set of testing functions,TestCase
has gained two
new functions:
precreate_tempfiles()
will generate a specified number of temporary
filenames (usingmake_tempfile()
), spy onmake_tempfile
, and then
return that list. The list of temp filenames are also returned to the
caller. This allows the caller to pre-generate some command
executions or spy operations that may need to know those temp
filenames.
assertDiffEqual()
, which compares two diffs, ensuring both are
bytestrings and comparing the lines of each to ensure correct content
(or to make diffing of mismatches clear).Along with this,
maxDiff
was set to a high number, allowing assertion
failures that compare strings or lists to provide more useful
information, rather than truncating prematurely.kgb 6.1 is now required, in order to support the spy operation
functionality needed byprecreate_tempfiles()
.
Successfully made use of the new functionality in some upcoming unit tests.
