[Webtest] [dev] Memory Leak?

[Dierk Koenig]

Hi Ritesh,

all references are hold within the context of a testSpec at most.

Did you try to use a memory profiler?

I did some some memory profiling lately and took snapshots between
testSpec. It couldn't find a single single leaking byte.

As Lisa said, too large result files can be a problem because they
are parsed before adding to it. In any case it is good practice for
large testsuites to devide then into subsuites and let them
report in to different files. This way, you can also profit from
running them in parallel.

I'm always open to improve the codebase. Feel free to open a JIRA
issue and attach a patch. Sometimes our goal of avoiding
duplication leads to constructions that may appear convoluted.
That's the DRY vs KISS trade-off.

cheers
Mittie
