robotframework-okw4robot 0.5.5

Driver-agnostic Robot Framework keyword library core for GUI test automation (OKW4Robot).

OKW4Robot

Driver-agnostic keyword architecture for Robot Framework.

One unified set of keywords for different GUI technologies (Web/Selenium, Web/Playwright, Java Swing, ...) — the actual implementation lives in the respective driver package.

Deutsche Version: README_de.md

ISO/IEC/IEEE 29119-5:2024: OKW4Robot implements the international standard for Keyword-Driven Testing — structurally since 2003. See ISO 29119-5 Conformity.

Getting Started

1. Install the core

pip install robotframework-okw4robot

2. Install a driver package (e.g. Selenium)

pip install robotframework-okw-web-selenium

3. Write a Robot test

*** Settings ***
Library    okw_web_selenium.library.OkwWebSeleniumLibrary

*** Test Cases ***
Login Test
    StartApp      MyApp
    SelectWindow  LoginDialog
    SetValue      Username         admin
    SetValue      Password         secret
    ClickOn       Login
    VerifyValue   Status           Logged in

StartApp loads the app YAML. If the YAML contains a __self__ section with the adapter class, the adapter is started automatically — no separate StartHost needed.

Note: The test imports the driver library (OkwWebSeleniumLibrary), not OKW4RobotLibrary directly. The driver library inherits all keywords from the core.

---

Architecture: Delegation, Not Control

Keywords do not call adapter methods directly. Instead, they delegate to exactly one okw_* method on the widget:

Keyword SetValue "Name" "Smith"
    │
    ▼
widget = resolve_widget("Name")        # YAML locator → WebSe_TextField
widget.okw_set_value("Smith")          # Widget knows how.

The OkwWidget interface (in okw4robot) defines all okw_* methods with NotImplementedError. Driver packages implement them:

okw4robot (Interface)	okw-web-selenium (Implementation)
OkwWidget.okw_set_value()	WebSe_TextField.okw_set_value() → Selenium clear + input_text
OkwWidget.okw_click()	WebSe_Base.okw_click() → Selenium click_element
OkwWidget.okw_move_over()	WebSe_Base.okw_move_over() → Selenium ActionChains.move_to_element
OkwWidget.okw_exists()	WebSe_Base.okw_exists() → Selenium find_elements

Waiting for Values and Synchronization

Verify keywords automatically wait for expected values (with timeout and polling):

# Set timeout (optional, default: 10s)
SetOKWParameter    TimeOutVerifyValue    15

# Keyword waits up to 15s for the expected value
VerifyValue    Status    Logged in

Write actions (Click, SetValue, TypeKey, Select) check preconditions first: exists → scroll_into_view → visible → enabled → editable → until_not_visible
