Logical Test Components

Logical components are a type of component that you can add to a test using the Compose tab (aka Composer). To learn how to access the components and create a test using the Composer see Writing API Tests with the Composer.

What You'll Need

• A Sauce Labs account (Log in or sign up for a free trial license).
• An existing API Testing Project. For details on how to create one, see API Testing Quickstart.
• Familiarity with the API Testing Composer.

Logical Components

Each

Allows you to iterate over a collection of elements and execute the piece of code for each element.

Parameters

Fields
Expression	| REQUIRED | EXPRESSION | The path of the collection you want to iterate on.

ExamplesFor Each legs collection, checks if the nested vector item is an integer value.

Legs Collection Example

{
  "legs": [
    {
      "vector": 1
    },
    {
      "vector": 3
    }
  ]
}

If a collection is nested in another one, you need to refer to them as _1, _2, and so on.For Each flights collection nested in content item, checks if price.amount is an integer. Then, for Each legs array, a nested collection in the flights collection, checks if vector item is an integer value.

Nested Collection Example

{
  "content": {
    "flights": [
      {
        "price": {
          "amount": 100
        },
        "legs": [
          {
            "vector": 1
          },
          {
            "vector": 3
          }
        ]
      }
    ]
  }
}

- id: each
  children:
    - id: assert-is
      expression: _1.vector
      type: integer
  expression: payload.legs

- id: each
  children:
    - id: assert-is
      expression: _1.price.amount
      type: integer
    - id: each
      children:
        - id: assert-is
          expression: _2.vector
          type: integer
      expression: _1.legs
  expression: payload.content.flights

If

Allows you to run a specific piece of code only if a specific condition is met.

Parameters

Fields

| REQUIRED | EXPRESSION | The path of the collection you want to iterate on.

ExamplesIf payload.success is equal to true then the code within the element is executed, otherwise is skipped.If _1.intermediate exists then the code within the element is executed, otherwise is skipped. This is useful when the element is not always present.

Code View Examples

- id: if
  children:
  - id: assert-equals
    expression: payload.message
    value: Seats Available
  - id: assert-equals
    expression: payload.content.flightid
    value: ${id}
    type: string
  expression: payload.success == true

While

Allows you to run a block of assertions as long as a condition is valid.

Parameters

Fields
Expression	| REQUIRED | EXPRESSION | The condition that has to be met for the assertions block to be executed.

- id: while
  children:
  - id: comment
    text: Executes assertion until items are less than 5
