From 547fff27033a294d1639ee3f9125f775032f39f5 Mon Sep 17 00:00:00 2001 From: Ed Santiago Date: Wed, 14 Jul 2021 13:55:00 -0600 Subject: e2e tests: use Should(Exit()) and ExitWithError() e2e test failures are rife with messages like: Expected 1 to equal 0 These make me cry. They're anti-helpful, requiring the reader to dive into the source code to figure out what those numbers mean. Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I don't know if it spits out a better diagnostic (I have no way to run e2e tests on my laptop), but I have to fantasize that it will, and given the state of our flakes I assume that at least one test will fail and give me the opportunity to see what the error message looks like. THIS IS NOT REVIEWABLE CODE. There is no way for a human to review it. Don't bother. Maybe look at a few random ones for sanity. If you want to really review, here is a reproducer of what I did: cd test/e2e ! positive assertions. The second is the same as the first, ! with the addition of (unnecessary) parentheses because ! some invocations were written that way. The third is BeZero(). perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go ! Same as above, but handles three non-numeric exit codes ! in run_exit_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go ! negative assertions. Difference is the spelling of 'To(Not)', ! 'ToNot', and 'NotTo'. I assume those are all the same. perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go ! negative, old use of BeZero() perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go Run those on a clean copy of main branch (at the same branch point as my PR, of course), then diff against a checked-out copy of my PR. There should be no differences. Then all you have to review is that my replacements above are sane. UPDATE: nope, that's not enough, you also need to add gomega/gexec to the files that don't have it: perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}')) UPDATE 2: hand-edit run_volume_test.go UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places UPDATE 4: skip a test due to bug #10935 (race condition) Signed-off-by: Ed Santiago --- test/e2e/push_test.go | 47 ++++++++++++++++++++++++----------------------- 1 file changed, 24 insertions(+), 23 deletions(-) (limited to 'test/e2e/push_test.go') diff --git a/test/e2e/push_test.go b/test/e2e/push_test.go index cc7c67941..b7e8309fb 100644 --- a/test/e2e/push_test.go +++ b/test/e2e/push_test.go @@ -10,6 +10,7 @@ import ( .
