What should be code review or testing first?

Question

Work organization

Give advice on the organization of work.
At what point is it more correct to upload the task to the stage so that the tester can test. Right after the developer finished it, or already when the task was reviewed?
In both cases, either the work of the tester or the one who did the review may be in vain.
What is your company approach?

Answer 1

As a result of the review, the code may change dramatically, which may lead to new bugs and correction of existing ones.
Based on the results of testing, the code rarely changes significantly - usually some local bugs are corrected.
Full testing is usually a more resource-intensive process than a review.
Based on this - first review.

Answer 2

Depends on the approach. If you have tdd, then you have testing before the code or in parallel with it. By and large, the test does not depend on the code. Both depend on decomposition and TK.
