The client sabotages testing. What steps should be taken?

If the client sabotages testing, the following steps should be taken:

1. Identify the reasons for sabotage — there may be misunderstandings, fears, or conflicts of interest.
2. Explain the importance of testing for product quality and successful project completion.
3. Offer compromises or adapt the testing process to the client's needs.
4. Document all communications and attempts to conduct testing for transparency.
5. Involve interested parties (management, business analysts) to support and resolve the conflict.
6. Escalate the issue to higher authorities if necessary.

The main thing is to maintain professionalism, seek constructive dialogue, and strive for the overall success of the project.
