Question

I would like to write some integration test for my application. I wasn’t able to find some relevant information with examples on this subject so I’m asking here.

Let’s have a controller with a simple CRUD scenario.

There is a create method, edit method and delete method.

My question is how to design the test case.

I was thinking of two ways how to test it.

1.

• Test 1 Create item – just insert an item
• Test 2 Edit item – load the item from the first test and edit it
• Test 3 Delete item – delete the item used in Test 2 and 3.

In this case all tests are more like one big test case.

1. • Test 1 Create item – insert an item, check if it’s there and delete it.
   • Test 2 Edit item – insert an item,load the item, edit it and delete the item.
   • Test 3 Delete item – insert an item and delete the item

In this case the tests looks independent but they have some repetitive parts (inserts)

Answer 1

For the CRUD scenario you described, the test can be implemented with three separate database transactions and their associated assertions.

Step 1 – Insert an item

Step 2 – Assert that the item was inserted successfully

Step 3 – Edit the item

Step 4 – Assert that the item as edited successfully

Step 5 – Delete the item

Step 6 – Assert that the item was deleted successfully
