- "task 1" = active task

All filter

Active filter

All filter
- "a"
- "b"
+ "c"

assertTasks("a", "b", "c")
  tasks.filter(visible).shouldHave(texts("a", "b", "c"));
  

1 assertVisibleTasks with filter(visible)
+ pros
  + easy straightforward implementation

- cons
  - "n tasks"-number times slower at all filter context
  - lack of full control
  
Alternative >>

2 asserts for tasks: assertTasks for all filter and assertVisibleTasks for others

assertTasks
  tasks.shouldHave(texts("a", "b", "c"));
  
assertVisibleTasks
  tasks.filter(visible).shouldHave(texts("a", "b", "c"));
  
- cons
  - less straightforward way to implement step checks
  
+ pros
  + fast on all filter
  + more control during automation (using gray-box style techniques)
  

***

addTasks("a", "b", c")
toggleTask("a")
filterActive()
editTask("b", "b edited")
deleteTask("b edited")

Since the only entity in our app is tasks, we can omit it to make it more readable and clear >>

add("a", "b", c")
toggle("a")
filterActive()
edit("b", "b edited")
delete("b edited")





***

add("a", "b")
assertItemsLeft(2)

toggle("b")
assertItemsLeft(1)

edit("a", "a edited")

Summary:
-? after each action
   - less readable
   - too much of lower priority checks in smoke tests
   + nevertheless, better coverage
+- no
  + readable
+? after base actions (1-2 times)
  + pretty readable
  + at least somehow covered
