I just started experimenting with Siesta and wanted to port some of our Jasmine tests to Siesta.
I want to test for an error to be thrown. Somewhere in the code we call Ext.Error.raise (which will subsequently throw an error) and I wanted to check for this with throwsOk:
t.throwsOk(MyNamespace.lib.data.DateUtil.stringToDate('2012-04-19 11:30:24'),
/some error message/,
"When a string like '2012-04-19 11:30:24' is passed without a format string it must throw an exception");
But unfortunately, this test fails and the execution of all subsequent checks is stopped and I can see the message "test suite threw an exception" with my error message that I passed to Ext.Error.raise. I'm expecting throwsOk to catch the error and the test to pass. Am I doing something wrong?
And welcome, would be great to hear your feedback about Jasmine -> Siesta migration.
About your question - just supply the function to the `throwsOk`:
t.throwsOk(
function () {
MyNamespace.lib.data.DateUtil.stringToDate('2012-04-19 11:30:24')
},
/some error message/,
"When a string like '2012-04-19 11:30:24' is passed without a format string it must throw an exception"
)
Oh my, this is embarrassing. Of course it works now, thanks for the fast reply!
I'll keep you updated about the progress. What I can tell you so far is that I had everything up and running the way I wanted it (test cases in combination with the entire application running and visible in the background) in less than an hour instead of one day with Jasmine where I had to try a couple of different approaches first.
I met Mats today at the SourceDevCon and he mentioned something about a BDD layer that might be available in the near future. That's at the moment the main thing I would miss when migrating away from Jasmine. So I'm definitely looking forward to that.
