> Key: JBEHAVE-328
> URL: http://jira.codehaus.org/browse/JBEHAVE-328
> Project: JBehave
> Issue Type: Improvement
> Components: Core
> Affects Versions: 3.1
> Reporter: Mike Neeve
> Fix For: 3.x
>
> Attachments: jbehave-core.patch

>
> Attached is a patch for JBehave.
> The main change is the addition of a new parser. Its based on Eclipse JFace,
> which means we can track line numbers in error reporting. It can also be
> re-used for syntax highlighting in an Eclipse editor. JFace requires some
> Eclipse libraries, so these are new dependencies which still work even though
> we're not running in an OSGi container. The parser is also very fast compared
> to the current regex-based parser - the longest running test was 25s for the
> previous parser, and now its just 0.5s.
> In ScenarioParserBehaviour we've written some tests for the default
> configuration of JUnitScenario. They fail with the current parser but pass
> with the new one which is able to throw a new ParseException for each type of
> problem.
> We've added one test to CandidateStepBehaviour.java that currently fails.
> Doug tried fixing it by changing the ExamplesTable to be backed by a
> LinkedHashMap which means that the arguments are automatically in the correct
> order. But this did not work for other examples and couldn't figure out how
> to make it work, so the test is currently broken. We'd need help to fix this.
> Further proposed changes would improve the detection of problems such as:
> - not having enough columns in the examples section to cover all the required
> variables
> - having more columns than required in the examples section
> - checking the order of statements e.g. ensure a When comes after a Given
> - allowing boolean's for parameters
> The first two are quite difficult as it involves a good knowledge of the
> CandidateStep class.
