Hi all, I wrote this simple test case, but the result is always 'yellow' even if assertions are right (.st code attached). MyHtmlParserWarningTestCase>>testParserWarning1 | warning | warning := MyHtmlParserWarning new. self assert: (warning category isNil). self assert: (warning reason isEmpty). warning signal: #malformed reason: 'no close tag'. self assert: (warning category = #malformed). self assert: (warning reason = 'no close tag'). I think it is a bug on SUnit, so I put the issue 13242 on fogbugz. https://pharo.fogbugz.com/f/cases/13242/ I confirmed it is reproduced in Pharo 3.0.image and the latest image (Pharo-40000.image).
