Cron Expression is never executed

[paha77]

I have this environment variable:

DB_DUMP_CRON: "20 2 * * 0"

This supposed to be run At 02:20 on Sunday but is never executed.

Another expressions, like

DB_DUMP_CRON: "*/30 * * * *"

Are interpreted right and the dump process starts normally.

We have tests defined here:

	tests := []struct {
		name string
		cron string
		from string
		wait time.Duration
		err  error
	}{
		{"current minute", "1 * * * *", "2018-10-10T10:01:00Z", 0, nil},
		{"next minute", "1 * * * *", "2018-10-10T10:00:00Z", 1 * time.Minute, nil},
		{"next day by hour", "* 1 * * *", "2018-10-10T10:00:00Z", 15 * time.Hour, nil},
		{"current minute but seconds in", "1 * * * *", "2018-10-10T10:01:10Z", 59*time.Minute + 50*time.Second, nil}, // this line tests that we use the current minute, and not wait for "-10"
		{"midnight next day", "0 0 * * *", "2021-11-30T10:00:00Z", 14 * time.Hour, nil},
		{"first day next month in next year", "0 0 1 * *", "2020-12-30T10:00:00Z", 14*time.Hour + 24*time.Hour, nil}, // this line tests that we can handle rolling month correctly
	}

Even if you are not a golang person, the above should be reasonably straightforward. It is a list of tests:

• name (descriptive)
• cron expression
• "current" time
• wait

The tests are: if I entered that cron expression and the current time is "current time", how long should I expect to wait for it to trigger.

If you can give a test case that fits that, we can put it in, the test will fail, we fix it. Don't need it in any formal code structure, just a single descriptive test or two in human language that says, "if I put in the following cron expression ..... at the actual time ...., then it should wait .... and then trigger."
