Sure, I can help with that. For the purpose of this test case design, let's consider the "Create 3D Model" functionality in SketchUp.

1. Equivalence Partitioning:

Test Case 1: Description: Verify the ability to create a new 3D model using a valid file format. Input: Select "Create New 3D Model" -> Choose file format as .SKP (SketchUp file format). Expected Result: The new 3D model is created successfully with the .SKP file format. Justification: This test case covers the valid partition of file formats for creating a new 3D model.

Test Case 2: Description: Verify the handling of an invalid file format when creating a new 3D model. Input: Select "Create New 3D Model" -> Choose file format as .PDF (non-compatible file format). Expected Result: An error message is displayed indicating an invalid file format for creating a new 3D model. Justification: This test case covers the invalid partition of file formats for creating a new 3D model.

2. Boundary Value Analysis:

Test Case 3: Description Validate the behavior when creating a new 3D model with the minimum allowed dimensions. Input: Select "Create New 3D Model" -> Set dimensions to the minimum allowed values (e.g., 1mm x 1mm x 1mm). Expected Result: The new 3D model is created successfully with the minimum allowed dimensions. Justification: This test case covers the lower boundary of the dimensions for creating a new 3D model.

Test Case 4: Description: Validate the behavior when creating a new 3D model with the maximum allowed dimensions. Input: Select "Create New 3D Model" -> Set dimensions to the maximum allowed values (e.g., 1000mm x 100mm x 1000mm). Expected Result: The new 3D model is created successfully with the maximum allowed dimensions. Justification: This test case covers the upper boundary of the dimensions for creating a new 3D model.

3. Decision Tables:

Test Case 5: Description: Verify the behavior when creating a new 3D model based on the material type selected. Inputs:

• Material Type: Wood
• Texture: Oak
• Size: 10cm x 10cm x 10cm Expected Result: A new 3D model is created with the specified wood material and oak texture in the provided dimensions. Justification: This test case covers the combinations of inputs related to material type, texture, and size to validate the creation of a new 3D model.

These test cases cover different scenarios related to the "Create New 3D Model" functionality in SketchUp using black-box testing techniques, ensuring thorough testing of the feature.

Sure, let me add 2 more test cases, bringing the total to five. Here are some additional cases using error guessing and state transition techniques:

4. Error Guessing:

Test Case 5: Description: Verify the application's responsiveness when entering negative values for dimensions during new 3D model creation. Input: Select "Create New 3D Model" -> Set dimensions to negative values (-5mm x -5mm x -5mm). Expected Result: An error message is displayed indicating invalid input for dimensions model creation is not initiated. Justification: There could be a chance that users mistakenly enter negative numbers. This test case simulates that possible error to ensure the application responds appropriately.

5. State Transition:

Test Case 6: Description: Test the ability of the application to handle user changes from one state (editing a 3D model) to another state (creating a new 3D model) without saving the changes to the first model. Input: Initiate editing a 3D model -> Make some alterations Without saving changes, select "Create New 3D Model". Expected Result A prompt should show up warning the user about unsaved changes and asking whether to save the changes or discard them before creating the new model. Justification: Users might change functions or roles while using SketchUp; this test case ensures data is not lost due to such transitions, or at least users are alerted about possible data loss.

Sure, black-box testing only focuses on the inputs and expected outcomes without paying attention to the application's internal workings. Here are five cases using the SketchUp's 'Draw Line' feature.

1. Equivalence Partitioning:

Test Case 1: Description: Verify the ability to draw a line using valid coordinate inputs. Input: Select 'Draw Line' -> Choose start point (3,3) and end point (6,6). Expected Result: A straight line is drawn from one point to another. Justification: This confirms the 'Draw Line' function's proper operation in the valid partition.

Test Case 2: Description: Verify the handling of erroneous coordinate input. Input: Select 'Draw Line' -> Choose start or end point as 'aaa,bbb'. Expected Result: An error message is displayed, indicating incorrect coordinate input. Justification: This assesses how the 'Draw Line' function handles erroneous partition inputs.

2. Boundary Value Analysis:

Test Case 3: Description: Validate the behavior when drawing a line of minimum length, i.e., two identical points. Input: Select 'Draw Line' -> Choose start point (0,0) and end point (0,0). Expected Result: An error message indicating that the two points are identical and that a line cannot be formed. Justification: This checks the application's handling of a minimal-line scenario (boundary case).

Test Case 4: Description: Validate the behavior when drawing a line of maximum length (based on SketchUp's dimensional limits). Input: Select 'Draw Line' -> Choose start point (0,0) and end point (10000 mm, 10000 mm). Expected Result: A line is drawn from the start point to the end point. Justification: This evaluates the application's ability to draw the longest possible line (boundary case).

3. Decision Table:

Test Case 5: Description: Determine the system's behavior when attempting to draw a line while the software is in different possible states. Inputs:

• State: Currently a line.
• Action: Select 'Draw Line' and attempt to draw a new line without ending the first one. Expected Result: Either an error message should be displayed, alerting the user that he/she is currently drawing a line, or the first line should end at the starting point of the new line (based on program design). Justification: This case checks how the application handles complex scenarios involving user behavior and multiple states.

Certainly! A decision table for the "Draw Line" feature in SketchUp can help visualize the combinations of inputs and expected outcomes. Here's the decision table for test case 5:

This decision table covers the different combinations of conditions for the "Draw Line" feature in SketchUp, considering the current state and the user's action. Each combination leads to a specific expected result, giving a clear understanding of the system's behavior in various scenarios.

Certainly! Let's modify the Test Case 5 and create a decision tree for the revised scenario.

Revised Test Case 5: Description: Determine the system's behavior when attempting to draw a line while the software is in different possible states. Inputs:

• Current State: State of the application (Drawing a Line, Not Drawing a Line)
• Action: User's action to draw a line (Draw Line Again, Do Not Draw Line Again) Expected Result: Based on the combination of inputs, the expected outcome should be accurately determined.

Decision Tree for the Revised Test Case 5:

If Current State is Drawing a Line
|
|---> If Action is Draw Line Again
|       |
|       |---> Display error message: Cannot draw a new line while the current is in progress.
|
|---> If Action is Do Not Draw Line Again
|       |
|       |---> Continue drawing the current line.
|
If Current State is Not Drawing a Line
|
|---> If Action is Draw Line Again
|       |
|       |---> Start drawing a new line from the specified start point to end point.
|
|---> If Action is Do Not Draw Line Again
|       |
|       |---> No action needed as the user has chosen not to draw a new line.

The decision tree provides a visual representation of the possible states and actions, along with the corresponding expected results for the "Draw" feature in SketchUp. This helps in understanding the conditional logic and the outcomes based on the given inputs.

I see, please find the updated decision table for the revised Test Case 5 below:
