# tests/integration/steps
|
|
|
|
This test attempts to exhaustively try all interesting combinations of resource steps. This
|
|
includes:
|
|
|
|
* Same
|
|
* Create
|
|
* Update
|
|
* Delete
|
|
* CreateReplacement
|
|
* DeleteReplaced
|
|
|
|
in addition to the ability to recover from failures. For example, there is a "pending deletion"
|
|
capability that will remember resources that were meant to be deleted, but couldn't be, due to a
|
|
failure partway through.
|
|
|
|
The test is broken into a series of steps that will be executed in order. Because the steps create
|
|
different resources, we will end up with a specific sequence of CRUD operations that we will
|
|
validate.
|
|
|
|
# Step 1
|
|
|
|
Populate the world:
|
|
|
|
* Create 4 resources, a1, b1, c1, d1. c1 depends on a1 via an ID property.
|
|
|
|
Checkpoint: a1, b1, c1, d1
|
|
|
|
# Step 2
|
|
|
|
Same, Update, Same, Delete, Create:
|
|
|
|
* Create 1 resource, a2, equivalent to the a1 in Step 1 (Same(a1, a2)).
|
|
|
|
* Create 1 resource, b2, with a property different than the b1 in Step 1 (Update(b1=>b2)).
|
|
|
|
* Create 1 resource, c2, equivalent to the c1 in Step 1 (Same(c1, c2)).
|
|
|
|
* Elide d (Delete(d1)).
|
|
|
|
* Create 1 resource, e2, not present in Step 1 (Create(e2)).
|
|
|
|
Checkpoint: a2, b2, c2, e2
|
|
|
|
# Step 3
|
|
|
|
Replace a resource:
|
|
|
|
* Create 1 resource, a3, with a property different than the a2 in Step 2, requiring replacement
|
|
(CreateReplacement(a3), Update(c2=>c3), DeleteReplaced(a2)).
|
|
|
|
* Elide b (Delete(b2)).
|
|
|
|
* Create 2 resources, c3 and e3, equivalent to Step 2 (Same(c2, c3), Same(e2, e3)).
|
|
|
|
Checkpoint: a3, c3, e3
|
|
|
|
# Step 4
|
|
|
|
Replace a resource (but this time, deleteBeforeReplace):
|
|
|
|
* Create 1 resource, a4, equivalent to the a3 in Step 3 (Same(a3, a4)).
|
|
|
|
* Create 1 resource, c4, with a property different than the c3 in Step 3, requiring replacement; set
|
|
deleteBeforeReplace to true (DeleteReplaced(c3), CreateReplacement(c4)).
|
|
|
|
* Create 1 resource, e4, equivlaent to the e3 in Step 3 (Same(e3, e4)).
|
|
|
|
Checkpoint: a4, c4, e4
|
|
|
|
# Step 5
|
|
|
|
Fail during an update:
|
|
|
|
* Create 1 resource, a5, with a property different than the a4 in Step 4, requiring replacement
|
|
(CreateReplacement(a5), Update(c4=>c5), DeleteReplaced(a4)).
|
|
|
|
* Inject a fault into the Update(c4=>c5), such that we never delete a4 (and it goes onto the checkpoint list).
|
|
|
|
Checkpoint: a5, c5, e5; pending delete: a4
|
|
|
|
# Step 6
|
|
|
|
Delete everything:
|
|
|
|
* Elide a (Delete(a5)).
|
|
|
|
* Elide c (Delete(c)).
|
|
|
|
* Elide e (Delete(e)).
|
|
|
|
* Pending delete (Delete(a4)).
|
|
|
|
Checkpoint: empty
