tool_task_cronrunning has very tight limits on checking cron interval and expected frequency

Setup

1. Make sure the expected cron frequency is set to 60 seconds

   $ php admin/cli/cfg.php --name=expectedcronfrequency --set=60

Test

1. Run the cli script for the Check API and confirm it is OK. If it's not OK, run a couple of times the cron job ($ php admin/cli/cron.php) and re-run the CLI script for the Check API (after this, it should return OK).

   $ php admin/cli/checks.php

   OK: All 'status' checks ok

2. Confirm that the shell error code was 0:

   $ echo $?

   0

3. Simulate a gap of 130 seconds between two consecutive cron runs and confirm it reports a warning for tool_task_cronrunning

   $ php admin/cli/cfg.php --component=tool_task --name=lastcroninterval --set=130

   $ php admin/cli/checks.php

   WARNING: Cron running (tool_task_cronrunning)

   Status | Check

   ----------+--------------------------------------------------------------------

   WARNING | Cron running (tool_task_cronrunning)

   | There was 2 mins 10 secs between the last two runs of the

   | cron maintenance script and it should run every 1 min. We

   | recommend configuring it to run more frequently.

4. Confirm that the shell error code was 1:

   $ echo $?

   1

5. Simulate a gap of 90 seconds between two consecutive cron runs and confirm it is OK

   $ php admin/cli/cfg.php --component=tool_task --name=lastcroninterval --set=90

   $ php admin/cli/checks.php

   OK: All 'status' checks ok

6. Confirm that the shell error code was 0:

   $ echo $?

   0
