Gherkin Language

Correct Answer: The syntax is not correct and suggest improvements like: 'Given there is a field to enter data, When the data is entered, Then the database is updated with the entered data.'

The Gherkin language is designed around the Given-When-Then structure for writing behavioral tests. This structure helps us understand the initial context (Given), the event or action taken (When), and the expected outcome (Then). The mentioned colleague's Gherkin scenario doesn't follow this structure, making it less clear and less effective for implementing in techniques like Behavior-Driven Development. Hence, telling them about this error and suggesting improvements towards following this structure is ideal. Conversely, the remaining options are less appropriate. Suggesting to rewrite the scenario without the Given-When-Then structure would contradict the Gherkin rules. Agreeing with the wrongly formulated scenario and saying nothing about the incorrect syntax would lead to potential misunderstandings or errors later in the testing process. Finally, arranging a meeting with the whole team to discuss this specific scenario seems excessive, as it's an individual's error rather than a team-wide issue.

Correct Answer: Improve the scenario by splitting The 'Then' step into 'Then' and 'And' steps, such as: 'Then I should see the homepage, And my username is displayed.'

The best approach when dealing with scenario descriptions in agile development, specifically in Gherkin format, is to ensure they are as clear and detailed as possible. Thus, the answer stating that one should 'Improve the scenario by splitting The 'Then' step into 'Then' and 'And' steps, such as: 'Then I should see the homepage, And my username is displayed.' is the most suitable. Detailed scenarios provide a clear understanding for all team members, which helps avoid misinterpretations during development. Ignoring feedback and proceeding with the available information contradicts the agile principle of embracing changes for the customer's competitive advantage. Removing the login feature because it's too complicated doesn't align with problem-solving and delivery focus of an agile team. Lastly, asking non-technical team members to revise the scenario doesn't account for the need of having detailed and technologically sound scenarios, which they might struggle to provide.

Correct Answer: Install and implement the Gherkin language in your project to utilize highest levels of Behavior Driven Development (BDD)

The Given-When-Then structure is available in the Gherkin language, which serves a key role in Behavior Driven Development (BDD). If it's not available in your current Gherkin specification language, the best option would be to correctly install and implement the Gherkin language in your project. The idea of 'Switching to a different project management methodology' is not the best solution as it doesn't directly address the problem. BDD and Gherkin can be used with many different project management methodologies. 'Avoid using a Given-When-Then structure for your scenarios' is not an ideal solution since the Given-When-Then structure is a fundamental part of writing good, clear scenarios for BDD. Last, 'Inventing your custom Given-When-Then language' is not advisable as it could potentially lead to confusion and compatibility issues down the line. It's always preferable to use established and widely-adopted specifications and languages.
