Question: Adding tests for unformated HTML output

I am currently adapting version 0.11.2 of FastQC as a Galaxy tool, as we want to include it in our workflow. As currently only an older version of the tool is available on the Galaxy Toolshed we thought of making it public. Unfortunately writing (output file comparison) tests for the new version has proven difficult as it generates HTML output in a single line of text (no newline characters included in the ascii text document of ~300 KB). While it might be possible to include regular expressions for date and time stamps in the output, it seems difficult to provide a good test under this circumstance.

A possibility would be to include the .txt output of FastQC and compare that one to a sample. Does anyone with more experience in Galaxy testing have more suggestions?

Thank you,

Hi Philipp!

Thanks very much for updating the wrapper! The old fastqc wrapper is located here, including some test cases:

Hopefully this will help you! Can you please create a PR against this repository, we can merge it if you want and update the old wrapper with the new one.

Thanks again,

Hi Björn,

This is actually pretty much what I was doing (based on the iuc package that should be very similar to your package and including some changes from tmcgowan from the main testtoolshed).

Thanks, Philipp

The current version Bjoern refers to uses test syntax which allows date, filename and other variations in the HTML output each time the test is rerun, by allowing up to 100 lines to differ between the saved and the generated html - the trick is the lines_diff parameter in the test:

<output name="html_file" file="fastqc_report.html" ftype="html" lines_diff="100"/> 

There are some complexities in the companion python wrapper which munges the fastqc generated html directory/link structure to make it work properly as a Galaxy composite object Html page and I noticed in the update notes that there may have been changes to the file/directory structure of html output so there will probably be some changes needed. The tool_dependencies link and some references to version numbers will need updating but otherwise it should be fairly straightforward and as Bjoern has said, pull requests welcomed!

Yes, I have seen that. Unfortunatly the output for the new version is a single line, so "lines=diff='100' " does not work anymore. I thought about inserting a newline character between each '><' pair but did not want to change the output to much.

I just took a closer look at

Looks like the improvements require more work than I'd hoped.

If the images are embedded then the lines diff will need to allow for every base64 line. Not good.

Maybe the zip file contents are more tractable for creating the Html file output?

If so, then appending \n to <b> or <p> might give deterministic and countable lines to test.

Otherwise perhaps regexps for some headings or something similar ?

I've taken the liberty of starting
