'''ZDTM''' stands for '''Z'''ero '''D'''own'''T'''ime '''M'''igration. '''ZDTM test suite''' was developed for testing how OpenVZ live migration works. CRIU also uses this test suite.
The suite consists of many small atomic tests. Each test case creates a process, puts it into some specific state (opens a file, maps a memory segment, puts data in a pipe, etc.), then asks to be checkpointed and restored. Upon restoring, it checks that the state was preserved (file is still opened, memory is still mapped, pipe contains what was put into it, etc).
