From: ilja Date: Tue, 1 Nov 2022 14:31:29 +0000 (+0000) Subject: fix_flaky_transfer_task_test.exs (#237) X-Git-Url: https://git.squeep.com/?a=commitdiff_plain;h=be5044f785e562c4978121b74bce03f131b827e3;p=akkoma fix_flaky_transfer_task_test.exs (#237) There were async calls happening, so they weren't always finished when assert happened. I also fixed some bugs in the erratic tests that were introduced when removing :shout.:shout is a key where restart is needed, and was changed in the test to use :rate_limit (which also requires a restart). But there was a bug in the syntax that didn't get caught because the test was tagged as erratic and therefor didn't fail. Here I fixed it. During compilation, we had a warning `:logger is used by the current application but the current application does not depend on :logger` which is now fixed as well (see commit message for complete stacktrace).
