⏸️ 😳 🧘🏽 "Preparing for a QA interview" starter pack or the biggest test questions and answers cheat sheet 🔊 🍫 👶

The QA Bible is 200 ++ pages of an updated mixture of answers to questions from real interviews on QA, translation of interesting content from foreign resources and aggregation of material from domestic ones. Already at the initial stage, it has several thousand unique views of the repository and a huge positive feedback from the community, which gives some guarantees for those who doubt whether to trust this material or whether to contribute here.

ATTENTION! In order to see the entire material, you need to open the first or second part in the files on the github ( Manual part 1 or Manual part 2 ).

It turned out that it is practically impossible to provide such a volume to the public. Unfortunately, Habr is not yet able to parse source codes larger than 150kb, which would mean splitting the material into 8 articles (the developers promised to fix it, the task is already active).

First of all, I want to emphasize that at the moment this material from Jun - Junam, from intermediate - the same, but will be useful to all grades, especially since some of the material is far from the initial level. The quality of the material (especially the translation) will improve with the proofreading and community input.

As for sources and resources, the list is not complete. In the initial synopsis for myself, I did not save links, so if you see the author's content, please do not swear, write - I will add to the sources. I did not try to make the list of useful resources comprehensive, but only indicated those that were useful to me personally, in fact, there are many times more of them.

I also note that the material itself is still far from comprehensive. It is assumed that this is a kind of hybrid of answers to questions and basic theory, and here the topics are disclosed to the extent that is required in the interview. That is, there is a reference point and some kind of base, but if necessary, you dig further yourself. Each term, each topic appears to me as a three-dimensional object and it is not always possible to achieve understanding by looking straight ahead (one source). Sometimes you need to look from different angles (from different sources).

If you have something to fix or add - write to tg @ VA610 / create an issue / fork and commit! I will try to process any comments, any requests for missing topics as soon as possible!
