Generate the DevWeb script

This section describes how to use the Offline Script Generator tool to generate a DevWeb script from a HAR file.

To run the Offline Script Generator tool:

  1. Open a terminal window and change to the DevWeb root directory.

  2. Run the following command:

    OfflineGenerator -mode=<mode type> -level=<script level> -config=<path to config file> <path to source file> <destination path>

    with the following key values:

    mode

    Define the mode type (har), to indicate the format of the file used to generate the script.

    Note: There is also swagger mode, used to generate files from Swagger specifications. For details, see API testing with DevWeb.

    level

    (Optional)

    Define the script level to generate: a url-based script, or pages with a resource-based script.

    Value: url (default) or pages

    config

    (Optional)

    Provide the path to the configuration file from which to generate the script.

    Note: If not provided, the default configuration file for this tool, generator_config.yml (located in the DevWeb root folder), is used. For more details, see Offline Script Generator configuration file (generator_config.yml) below.

    <path to source file> Provide the full path to the HAR file from which to generate the script.
    <destination path> Provide the full path to the folder in which to save the generated script.

    OfflineGenerator -mode=har -level=pages myFile.har Scripts/MyScriptDirectory

  • In the following example, pages with a resource-based script are generated from a HAR file, using a configuration file:

    OfflineGenerator -mode=har -level=pages -config=config/file.yml OfflineGenerator/input/HAR/json_pages.har C:\jsonPages
