ALEX 1.7.0

Breaking Changes

  • Removed the HTML Element Picker. The picker only really worked in Chrome and then only in some selected use cases, i.e. static pages. Due to these restrictions we decided to remove it completely.
  • Removed xvfb option. The option was introduced when major browsers did not have a headless mode. Since the option only worked on Linux systems and all major browsers have such a mode, the option has been removed.

ALEX 1.6.0

Breaking Changes

  • Symbols have to be migrated to the new version. Please use the migration script src/main/resources/migration/1.6.0/migrate-symbols-1.5.0-to-1.6.0.js via:

    node migrate-symbols-1.5.0-to-1.6.0.js ./symbols-from-1.5.0.json ./symbols-for-1.6.0.json

  • Tests have to be migrated to the new version. Please use the migration script src/main/resources/migration/1.6.0/migrate-tests-1.5.0-to-1.6.0.js via:

    node migrate-tests-1.5.0-to-1.6.0.js ./tests-from-1.5.0.json ./tests-for-1.6.0.json

Features

  • Symbols can be composed of other symbols.
  • Symbols can be parameterized in learning experiments.
  • Connect ALEX to a MySQL database. See the README for instructions.
  • Generate test suites from discrimination tree based learners (TTT, Discrimination Tree).
  • Use test cases in test suites as equivalence oracle.
  • Added support for Internet Explorer
  • Execute JavaScript asynchronously
  • Symbol parameters can be public or private. If a parameter is public, its value can be set by the user while configuring a testing or learning process. If it is private, its value cannot be set manually, but is resolved by the value in the global data context.

ALEX 1.5.1

This release only contains some bug fixes.

ALEX 1.5.0

Breaking Changes

  • Symbols and tests that have been exported with v.1.4.0 and lower can not be imported directly. Apply the new export format and for each symbol in an exported JSON file add the properties inputs and outputs so that the resulting file looks like:

    {
  "version": "1.4.0",
  "type": "symbols",
  "symbols": [
    {
      "name": "symbol",
      ...,
      "inputs": [],
      "outputs": []
    },
    ...
  ]
}

Bug Fixes

  • Resuming a learning process should now work as expected.
  • Various smaller fixes.

Features

  • The results of test executions are saved in reports.
  • Added webhooks to notify external applications about changes.
  • Reuse the browser instance for membership queries. A hard reset with a new browser instance can be achieved with a new action.
  • New actions:
    • Refresh and restart the browser window.
    • Click on a arbitrary element with a given visible text.
    • Check if an element, e.g. a checkbox, radio button or option is selected.
    • Set variable to HTTP response body.
  • Parameterized symbols: symbols now have dynamic inputs and outputs. Values for inputs can be set by a user for modelling tests.
  • Symbols and symbol groups can be nested in a tree like structure.
  • Named project URLs.
