I'm new to unit testing, and I'm learning how to use NUnit and Moq. NUnit provides Assert syntax for testing conditions in my unit tests, while Moq provides some Verify functions. To some extent these seem to provide the same functionality.
How do I know when it's more appropriate to use Assert or Verify?
Maybe Assert is better for confirming state, and Verify is better for confirming behavior (Classical versus Mockist)?

In the case of the “Assert” command, as soon as the validation fails the execution of that particular test method is stopped. Following that the test method is marked as failed. Whereas, in the case of “Verify”, the test method continues execution even after the failure of an assertion statement.
Assert: If the assert condition is true then the program control will execute the next test step but if the condition is false, the execution will stop and further test step will not be executed. whereas, Verify: There won't be any halt in the test execution even though the verify condition is true or false.
The assertAll() method is called to throw all the exceptions caught during the process of Selenium test automation execution. Soft Asserts are not included by default in the TestNG framework. You have to include the package org.
Assertions are used to validate the message received by a TestStep during execution, usually by comparing parts of the message (or the entire message) to some expected value. Any number of assertions can be added to a sampler TestStep, each validating some different aspect or content of the response.
Your assumption about Assert to confirm State and Verify to confirm behavior is correct.
You Assert a result, or a value
You Verify that a method has been called with appropriate parameters.
