 get baseline image count

get baseline image count

Description

Retrieve a count of the total number of baseline images that reside in a given picture check.

Arguments

• picture

  Name of a regular or shared picture check.

• variable

  (Optional) Variable to receive the returned value.

Valid contexts

This action may be used within the following project items: test modules and user-defined actions.

Applicable Built-In Settings

The following settings are applicable to this action: remove double quotes from cells.

Applicable Systems/Platforms

Use of this action is supported on the following system(s)/platform(s): Windows, Linux.

Notes

• picture argument: Identifies the name of a regular or shared picture check (learn more), with the forward slash (/) as the path separator.
  • If the target image is in a shared picture check, the path starts with the forward slash (/), which corresponds to the Picture Checks subfolder of the project, followed by picture’s name.
  • If the target image is in a regular picture check, the path starts with picture’s name.
• variable argument:
  • If the variable in argumentvariablehas not been declared, the action creates it as a global.
  • If the variable argument is left empty, TestArchitect supplies a global variable with the name _result.
• This built-in action can be applied to pre-process baseline and runtime images, before actually integrating them with a given third-party image processing tool for further processing. (See Example below.)
• This action supports the <ignore> modifier. If the string <ignore> is present as the value of any of the arguments, or any argument contains an expression that evaluates to <ignore>, the action is skipped during execution.

Result

Example - Case 2: Integrating with a third-party image processing tool

In this example, the ImageMagick v.6.9.3-7 tool is invoked for further image processing.

Suppose that you’d like to compare the baseline image against the runtime image, but ignore the differences in their color.

A basic workflow is as follows:

1. Capture the runtime image in the AUT, and then save it to a local path by using capture screen.
2. Retrieve the total number of baseline images in a given picture check by using get baseline image count.
3. Loop through the list of returned baseline image(s).
4. Export the baseline images to a file with export baseline picture.
5. Use ImageMagick CLI to preprocess and compare the baseline image(s) against the runtime image.
6. Get the returned value from ImageMagick, and then check it against an expected value.
