How to learn software testing from 0?

1, if you are a fresh graduate, you generally won't have this problem. Anyway, no matter what position you do, you start from the foundation of 0, so LZ should have worked.

2. In order to change careers;

It is very important to learn the basic knowledge of testing before buying a software test book.

Start practicing by yourself according to the contents in the book (how to practice? Download a software yourself or find a website to start)

After completing the second step above, you know more or less about the examination process and knowledge.

Then you can start looking for a job. Before looking for a job, look at what products the other company makes, and then take their products back. Run the test process yourself and record all bugs (don't say there are no bugs, every product has bugs). When sending resumes, you can send bugs of their products together.

More on the 5 1 exam forum, plus several exam Q groups, forums and Q groups, you will often see the recruitment of primary exams.

There is another plan; IT's easier to transfer jobs within your company (I just transferred from IT department to testing department).

But you have to learn the above exam knowledge yourself, and don't expect to start learning after jumping ship.
