how do I get historyThreshold to work

[Bilal]

I have configured maven witht he clover plugin and I REALLY like it so far. But I seem to have issues with the <historyThreshold/> tag.

This is my configuration:

<configuration>
<licenseLocation>/Users/bclarance/Downloads/clover.license</licenseLocation>
<!-- How to specify the coverage threshold -->
<targetPercentage>70%</targetPercentage>
<!-- How to specifiy historical threshold -->
<historyThreshold>1%</historyThreshold>
<!-- How to specify what typeds of reports to generate -->
<generateJson>true</generateJson>
<generatePdf>true</generatePdf>
<generateXml>true</generateXml>
<generateHtml>true</generateHtml>
<!-- how to evaluate coverage -->
<instrumentation>statement</instrumentation>
<!-- when using context you have to add the filters -->
<contextFilters>private,log</contextFilters>
<!-- how to generate historical code coverage and define a dir for it -->
<generateHistorical>true</generateHistorical>
<historyDir>${user.home}/history/${project.artifact}</historyDir>
</configuration>

When I build my clover report at 90% code covereage and then build a subsequent one 85% I would expect it to fail, but it doesn't. Firstly, becasue it meets the targetPErcentage, but I still need it to fail if there is a code coeverage drop too large, in this case only 1% to validate the failure.

Pelase help if you have any ideas.

Hi Bilal,

Please have a look at documentation of historyDir and historyThreshold attributes:

Allows you to specify a location for historical build data, along with a configurable threshold expressed as a percentage used to cause the build to fail if coverage has dropped. This attribute is passed down to specified packages, then the same test is done for these at the package level. This will only be used if there is no targetPercentage parameter set.

As you can see you cannot use targetPercentage and historyThreshold in the same configuration. However, you can create two separate profiles with different configurations:

• one for clover2:check with targetPercentage defined
• one for clover2:check with historyThreshold defined

This will work.
