Filter Step applyFilters

Description

Applies one or more filters to the current response and treats the result as if it was a new response.

This step allows you to apply one or more filter(s) to the current response and then perform some simple tests on the result as if the filtered result is a new response.

This step should be treated as experimental. It does a few hacks under the covers but has been very useful for debugging purposes. If you use this step, a recommended approach is to not perform subsequent invokes after this step, i.e. this step should be near the end of your test sequence.

Parameters

description
Required? no
The description of this test step.
htmlId
Required? no
The id of an HTML element. If present, processing will be limited to this element. Will be ignored if a nested table step is used.
save
Required? no
A shorthand: save='prefixName' is the same as savePrefix='prefixName' saveResponse='true'.
savePrefix
Required? no, default is the 'savePrefix' parameter as specified in <config>.
A name prefix can be specified for making a permanent copy of received responses. A unique number and the file extension (depending on the MIME-Type) will be appended. The resultpath attribute of the <config> element is used for determining the location of the saved result.
saveResponse
Required? no
Whether to make a permanent copy of received responses. Overrides the default value set in the <config> element.
xpath
Required? no
An XPath expression identifying an HTML element. If present, processing will be limited to this element. Will be ignored if htmlId is set or if a nested table step is used.

Nested Parameters

step
Required? yes
A webtest step.
table
Required? no
To locate a specific cell in a specific table on the page.

Details

The following example illustrates how to use the applyFilters step:

applyFilters example
<steps>
    <invoke url="testDocBookmarks.pdf"/>
    <applyFilters>
        <pdfToTextFilter mode="groupByLinesdescription="extract PDF text (default mode: normal)"/>
        <lineSeparatorFilter description="normalise line separators"/>
    </applyFilters>
    <verifyText text="Heading Two"/>
    <verifyText text="NEW PAGE"/>
</steps>

Remember that the resulting filtered response doesn't correspond to what your application is actually producing so keep your usage of this step to a minimum.
