Test suite: Start New Line and Split Line

Setup: Type String str = "abcde 123456"; inside a method's body

  1. Smart Enter inside strings
    1. Move caret behind the "abcde"
    2. Press Enter
    • EXPECTED RESULT: If Enter is pressed inside of a string, the string is smartly divided using '+' operator above strings so that there are no errors in code
      Other info:
      - indentation works normally
      - all white characters are preserved
      - caret is moved behind the opening quote
  2. Undo,Redo and a smart Enter
    1. Follow previous testcase
    2. Invoke Undo and Redo several times
    • EXPECTED RESULT: Undo and Redo is working properly.
  3. Start new line
    1. Move the caret behind "abcde"
    2. Press Shift+Enter.
  4. Undo/Redo start new line
    1. Try to use Undo and Redo
    • EXPECTED RESULT: Undo/Redo works properly.
  5. Split line
    1. Move caret behind "abcde"
    2. Press Ctrl+Enter
  6. Undo/Redo split line
    1. Try to use Undo and Redo
    • EXPECTED RESULT: Undo/Redo works properly

Test suite: Erroneous Code

  1. Show tooltip
    1. Paste this incorrect field declaration inside a class body: public private int a0;
    2. Hover with mouse cursor over error annotation mark in gutter for a while (wait for tooltip to appear).
    3. Place caret on marked line and press Alt+Enter
      - Erroneous code should be underlined
      - A red annotation mark shows up in the gutter
      - A tooltip should be displayed after you hover above the annotation mark and after you press Alt+Enter, tooltip contains error "Illegal combination of modifiers: private and public"
  2. Cycling through annotations
    1. Use the incorrect field declaration public private int a0; from the previous test case
    2. Place caret on the line with the incorrect code and press Ctrl+F8 (toggle breakpoint→breakpoint is inserted)
    3. Press Ctrl+Shift+M (toggle bookmark→bookmark is inserted)
    4. You should see a little arrow by the annotation in the gutter - click it a few times
    5. Press Ctrl+F8 (toggle breakpoint→breakpoint is removed)
    6. Press Ctrl+Shift+M (toggle bookmark→bookmark is removed)
    • EXPECTED RESULT: The arrow is used for cycling among multiple annotations, so that you can see all annotations. In this case there should be 3 annotations: the bookmark, the breakpoint and error annotation.

Test suite: Java Abbreviations



    1. Check if abbreviations work properly (you can check the list of all abb. in main window, Tools|Options| Editor| Code Templates)
    2. Try using of abbreviation inside comments
    3. Try abbrev inside string literal
    • EXPECTED RESULT: Abbreviation should work inside comments and strings literal as well
  1. Adding Abbreviation
    1. Add an abbreviation using Tools|Option|Editor, select Java Language, click on New.
    2. In the "Abbreviation:" field, fill "myabb" in, confirm , and type "System.out.println("myAbbreviation");" inside text area labeled "Expanded Text:" for newly created abbreviation.
    3. Close options
    • EXPECTED RESULT: The 'myabb' abbrev should be replaced by 'System.out.println("myAbbreviation");'
  2. Change Abbreviation
    1. Change name of an abbreviation
    2. Change its text
    3. Try using this altered abbreviation
    • EXPECTED RESULT: Name and text should be altered properly
  3. Remove Abbreviation
    1. Remove some abbreviations from the abbreviations list
    2. Try to use them in editor
    • EXPECTED RESULT: All abbreviations should be deleted properly.
  4. Abbreviation With Cursor
    1. Add an abbreviation with cursor position specified. (e.g the expanded text contains '${cursor}' text )
    • EXPECTED RESULT: Abbrev should be inserted properly, with caret positioned on place specified in its description.
  5. Abbreviation - Negative cases
    1. Try to add an abbreviation with existing name
    • EXPECTED RESULT: User is informed that abbreviation with this name already exists and action is blocked

Test suite: Code Templates

Purpose: Tests the code templates functionality inside NetBeans editor.

Setup: Opened any file in editor and focus should be in editor window.

  1. Code Template Invocation from Abbreviation
    1. Type into editor "fori".
    2. Press tab.
    • EXPECTED RESULT: Code template for the for() cycle with iteration variable i should appear.
  2. Code Template Invocation from Code Completion
    1. Type into editor "for".
    2. Press Ctrl-Space to invoke code completion.
    • EXPECTED RESULT: Several variants of for cycle should appear (over array and over collection). It is possible to choose one of them and cycle using tab through the editable fields.
  3. Traversing through Code Templates
    1. Invoke the fori code template.
    2. Cycle through the editable fields by pressing Tab.
    3. Cycle back through editable fields by pressing Shift-Tab.
    4. Try to edit various fields from code template.
    5. Once outside code template try to edit the code inside the for cycle.
    • EXPECTED RESULT: It should be possible to cycle through the template in both directions. Editing should work properly and shared variable should be changed in all appropriate places.
  4. Defining Custom Code Templates
    1. Open new Options dialog and go to Editor | Code Templates.
    2. Add a code template called forx with code: TBD
    3. Try to invoke the new code template by both code completion and as an abbreviation.
    • EXPECTED RESULT: In both cases the template should be filled in and should work properly.
  5. Code Template Keywords
    1. Try to create a custom code template.
    2. Use any abbreviations and take advantage of as many parameters as possible. Parameters are described here: http://editor.netbeans.org/doc/UISpecs/CodeTemplates/spec.html
    • EXPECTED RESULT: Newly defined code templates work properly. All parameters work as expected.
  6. Standard Abbreviations
    1. Type into editor "wh" and press Ctrl-Space to invoke code completion.
    2. Try invoking all available abbreviations from code completion.
    3. Try all these abbreviations by typing the abbreviation and pressing tab.
    • EXPECTED RESULT: All abbreviations should be filled in properly.
  7. Types in code templates
    1. Declare 3 arrays - a1 of type String, a2 of type Integer and a3 of different type
    2. Below declaration type fori and press key for expanding code template -> the name of one array is inserted into teplate
    3. Press tab to get to array name and change to to different existing name (a3 -> a2, etc...) -> the template is changed, reflecting type of arrays element
    4. Change the array name to non-existing name or not compatible type -> cast is added
    • EXPECTED RESULT: Results are inline.
  8. Change Expand key
    1. Open Tools -> Editor -> Code Templates
    2. Change Expand Key to space
    • EXPECTED RESULT: The abbreviations are now expanded by space and not tab
  9. Block templates
    1. Select part of code (have to be complete statement, e.g. one line inside method body)
    2. Press alt-enter
    3. Select some template and confirm by enter
    • EXPECTED RESULT: The selected code is wrapped by specific template
  10. Block templates - custom template
    1. Create new template containing ${selection}, define description for it
    2. Select part of code (needn't to be complete statement as in previous test case)
    3. Press alt-enter
    4. Select new template and confirm by enter
    • EXPECTED RESULT: The selected code is wrapped by specific template

Test suite: Commenting code

  1. Toggle line comment
    1. Open any java file
    2. Try to comment and uncomment several lines by pressing CTRL+'/'
      - The selected lines should be commented by //.
      - If only commented lines are selected the action will uncomment them.
  2. Comment/Uncomment line
    1. Try to comment/uncomment lines using comment and uncomment buttons in editor toolbar
    • EXPECTED RESULT: Comment button should add '//' at the beginning of line, the uncomment button will remove it.

Test suite: Error stripe

Purpose: Error stripe is stripe right to the editor, it provides quick status of the opened file (small color box at the top of the error stripe) and highlights significant lines (lines with error, bookmark, caret position). It also provides quick navigation to the highlighted lines.

Setup: Opened any java file in editor

  1. File is OK
    1. Open java file without any errors or warnings.
    2. Remove all bookmarks, breakpoints, mark occurrences etc...
    • EXPECTED RESULT: The status box is green, the error stripe
  2. File with errors
    1. Open java file from the previous testcase
    2. Add code with warning (e.g. override toString method w/o @Override annotatino)
    3. Add another warning (e.g unused import)
    4. Add some code with error
    5. Remove all warnings/errors
    • EXPECTED RESULT: When file contains warning the status box is yellow, in the error stripe is yellow mark. When there is error in the file the status box is red and there is red mark in the errors stripe. Whenever mouse is hovering over the status box the info about status is shoew (e.g. "1 error(s) 2 warning(s)"). After removing the
  3. Caret position
    1. Open file which is longer than editor window
    2. Try scroll to beginning and end of the document (by arrows, pg up/down and scroll wheel)
    • EXPECTED RESULT: The caret symbol in error stripe (thin line with little square in the middle) moves to proper places when scrolling. When the caret is in the beginning of the document the symbol is in the top of error stripe, when the caret is at the end, the symbol is at the bottom.
  4. Error stripe navigation
    1. Open java file
    2. Put several bookmarks in the file and/or use mark occurrences feature
    3. Click on marks in error stripe
    • EXPECTED RESULT: The file is scrolled to show related place in editor, when hovering over the mark the mouse cursor is changed to tooltip informs about the type of the mark
  5. Error stripe navigation
    1. Open java file
    2. Put bookmark in it
    3. Put break point in it
    4. Add code with warning
    5. Add code with error
    6. Change line, add line, remove some lines (if the document is under version control)
    7. Turn on mark occurrences and put cart over identifier with more occurrences
    • EXPECTED RESULT: All this actions adds mark in error stripe, these marks differ by color - errors are red, warnings yellow, bookmarks dark gray, changed lines blue, removed lines ping, new lines green, etc...

Test suite: Java Macros



  1. Create Macro
    1. Start macro recording (Ctrl+J S or from editor toolbar)
    2. Write some text in editor, move cursor and try to invoke some formatting actions (Shift Line, Comment etc.)
    3. Finish recording macro (Ctrl+J E or in editor toolbar)
    4. Inside appeared dialog, type new macro's name and choose some keybindings for it.
    5. Open java source file into editor and try using new macro's keybinding.
    • EXPECTED RESULT: Macro should be added to the list and properly works.
  2. Create Macro in Options
    1. Open Tools|Options|Editor|Macros
    2. Click to Add button and create new macro

    4. Open Tools|Options|Editor|Macros
    5. Change the shortcut of macro created in previous testcase to Alt-P
    6. Change the shortcut of macro created in previous testcase to Alt-M (or other free shortcut)
    • EXPECTED RESULT: User is warned if trying to set already used shortcut. The shortcut is changed after 3. step and macro can be invoked by new shortcut in editor (the old one is not working any more)

Test suite: Line tools

Purpose: This suite tests tool for manipulating with whole line or several lines.

Setup: Opened any file in editor

  1. Move one line
    1. Put caret in document
    2. Press Alt-(Shift)-Up / Alt-(Shift)-Down (Netbeans 6.0 use Shift, NB 5.5 don't)
    • EXPECTED RESULT: Actual line is moved one line up/down
  2. Move selection
    1. Put caret in document
    2. Select several lines
    3. Press Alt-Up / Alt-Down

  3. Copy line
    1. Put caret in document
    2. Press Ctrl-Shift-Up / Ctrl-Shift-Down
    • EXPECTED RESULT: The actual line is duplicated below/above current line
  4. Copy block
    1. Put caret in document
    2. Select several lines
    3. Press Ctrl-Shift-Up / Ctrl-Shift-Down
    • EXPECTED RESULT: The whole selection (including whole partly selected lines) is duplicated below/above current selected block

Test suite: Smart Brackets

  1. Smart pairs
    1. Type private String[[ in body of class
    2. Push Backspace key
    3. Type private String S = new String( in body of class
    4. Push Backspace key
    5. Type if((11=11) & (2==3|) in an empty body of a method (place caret as suggested by '|')
    6. Press ')' key twice
      - When you press ')' for the first time, a new bracket is inserted after '3', so that brackets are correctly balanced. When you press ')' for the second time, the bracket is skipped (again - in order to keep number of closing/opening brackets balanced).
  2. Enter after opening curly bracket
    1. Move caret inside a method.
    2. Type if (true) {
    3. Push Enter key
    • EXPECTED RESULT: The closing bracket should be added automatically and indented properly
