When using the TestCaseSource attribute in nunit ncrunch does not always detect all the cases.

All the cases are detected with visual studio test runner.

And ideas or is this a bug?

Thank in advance

this my code

namespace XMLDataExtractorTests
{
[TestFixture]
internal class XMLRetrieverTests
{
public static List<object[]> _metricCases = new List<Object[]>
{
new object[]
{
TestUtilities.Metrics[ 0 ], ApplicationMetricsFile, ApplicationMetricsSql
},
new object[]
{
TestUtilities.Metrics[ 1 ], RuleResultFile, CodeRuleResultSql
},
new object[]
{
TestUtilities.Metrics[ 2 ], RuleResultFile, CodeRuleResultSql
},
new object[]
{
TestUtilities.Metrics[ 3 ], RuleResultFile, CodeRuleResultSql
},
new object[]
{
TestUtilities.Metrics[ 4 ], RuleResultFile, CodeRuleResultSql
},
new object[]
{
TestUtilities.Metrics[ 5 ], RuleResultFile, CodeRuleResultSql
},
new object[]
{
TestUtilities.Metrics[ 6 ], RuleResultFile, CodeRuleResultSql
},
new object[]
{
TestUtilities.Metrics[ 7 ], RuleResultFile, CodeRuleResultSql
}
};

[TestCaseSource( "_metricCases")]
public void GetXmlDocument_GivenMetric_ReturnsXDocumentContainingMetric( Metric metric, string filePath, string sql )
{
......
}

[TestCaseSource( "_metricCases" )]
public void GetXmlDocument_GivenMetric_CallsCorrectMethodWithCorrectSqlInSqlHelperWrapper( Metric metric, string filePath, string sql )
{
....
}
}
}

so it only runs the first few test cases but using the visual studio test runner it works fine.

Thanks in advance
