This diff adds the prototype websteps implementation that used to live at https://github.com/ooni/probe-cli/pull/506. The code is reasonably good already and it's pointing to a roaming test helper that I've properly configured. You can run websteps with: ``` ./miniooni -n websteps ``` This will go over the test list for your country. At this stage the mechanics of the experiment is set, but we still need to have a conversation on the following topics: 1. whether we're okay with reusing the data format used by other OONI experiments, or we would like to use a more compact data format (which may either be a more compact JSON or we can choose to always submit compressed measurements for websteps); 2. the extent to which we would like to keep the measurement as a collection of "the experiment saw this" and "the test helper saw that" and let the pipeline choose an overall score: this is clearly an option, but there is also the opposite option to build a summary of the measurement on the probe. Compared to the previous prototype of websteps, the main architectural change we have here is that we are following the point of view of the probe and the test helper is much more dumb. Basically, the probe will choose which redirection to follow and ask the test helper every time it discovers a new URL to measure it w/o redirections.

Directory github.com/ooni/probe-engine/experiment
This directory contains the implementation of all the supported experiments, one for each directory. The OONI spec repository contains a description of all the specified experiments.
Note that in the OONI spec repository experiments are called nettests. Originally, they were also called nettests here but that created confusion with nettests in ooni/probe-cli. Therefore, we now use the term experiment to indicate the implementation and the term nettest to indicate the user facing view of such implementation.
Note that some experiments implemented here are not part of
the OONI specification. For example, the urlgetter
experiment is not in the OONI spec repository. The reason why
this happens is that urlgetter is an experiment "library" that
other experiments use to implement their functionality.
Likewise, the example experiment is a minimal experiment that does nothing and you could use to bootstrap the implementation of a new experiment. Of course, this experiment is not part of the OONI specification.
