+### Mocking function in scriptblock
+Unfortunately, we don't have a straightforward way to mock a function inside a scriptblock, but we could use some workarounds to accomplish this.
+
+warning：Mocking may not work correctly in Pester versions below v5, so this function is only supported in Pester v5. In earlier versions, you cannot run the mock together with the script.
