Tutorials

Getting Started
- Explain what this tutorial about
- By the end of this tutorial...(not sure) - You would be able to write moderate Groovy scripts in JMWE.

Basics of Groovy
- Skip this if you already know Groovy
- Detail few basic concepts of Groovy
  - if, for, closure, lambda expressions, safe-navigation operator etc
- References to Groovy tutorials (external)
Where do you write your Groovy script
- Add a post-function/scripted condition/scripted validator of JMWE
- Select "Groovy expression" option
- The Groovy editor is displayed - Rough introduction on Groovy editor and reference to its actual page.
Tutorial - My first Groovy script
- Fetch the key of the issue
- issue.getKey()
- Provide reference to the issue variable and the getKey() method
- What do you get as the output - Refer the expected value of each field type document.
- What can I do with this Groovy script result? - that is a String
  - Either add this as a comment/Set a field that expects a String as input.

Tutorial - How to write a condition - The result of a scripted condition is a boolean. It can be used either to Control the execution of a post-function or Control the availability of a condition or Validate the input during a transition.
- Simple condition - Check whether a text field is empty or not
  - issue variable - Reference to variables documentation
  - Standard field, Access standard field doc reference
  - Custom field, Access custom field doc reference
  - Compare the value to the required value
    - Use if() or
    - Optimize the code by returning the result of the comparison
- Check the current user is a specific user
  - currentUser is the variable. - Reference to variables documentation
  - Explain its return value, and how to get the name of the user. - Reference to User interface
  - Return the result of the comparison to the specific username
- Check the priority of the issue
  - issue variable - Reference to variables documentation
  - Standard field - Expected input type of this field - Refer expected field type document
  - Issue interface - getPriorityObject() or get("priority")
  - Priority interface - getName()
  - Standard field, Expected field type - Check the priority - Priority object
  - Since it is an object, it has properties to look up to
  - Priority interface- refer
Tutorial - Safe access a field - To explain on how to avoid null pointer exceptions
