As a team, review your test criteria and brainstorm possible methods to test your design. Come to a consensus on the testing method(s) that will result in useful data with which to effectively and objectively assess the performance of your product. Your testing method(s) should address some or all of the data needs that you described in 1.0 Test Criteria. Write a summary of the selected testing method(s) and the rationale for each. The use of human subjects, animals, or other living tissue is strongly discouraged. If you are considering this, stop now and talk with your instructor. You may need to rethink your tests. After agreeing on a general summary of the testing procedure, create a document to present your testing plan. Include the following in your Test Procedure Summary.

Incremental Testing Summary: Stress, Structure, Fitting, and Purification tests.
Testing Date: April 4-15 2022
Testing Location- Ms. Lopez Classroom
Purpose: Roomba Cover- Qualitative
We can test the component by how the circumference fits on top of the Roomba and if we can still press the power button for the Roomba. It must also perform as a durable base for our air purifier. When the air purifier is put flat on the Roomba cover and still allows for the turning on and off of the Roomba, then the component has given us successful results.
Roomba Side Cover- Qualitative
We can test the component by how it fits the circumference of the side of the Roomba and if it can still filter air, use its sensor, and charge itself. It must also be able to accommodate the hooks that will attach to the air purifier halo. If it allows for the purifier to be stabilized onto the Roomba with the hooks, then the component has given us successful results.
Air Purifier Halo- Qualitative
We can test the component by how it fits the top of the air purifier and how it fits the hooks in the Roomba side cover. If it allows for the Roomba to be stabilized to the Roomba, then the component has given us successful results.
Hooks(Upper, Lower)- Qualitative
We can test the component by how it is able to stabilize the Roomba and purifier to each other by their respective components. If it allows for the Roomba and purifier to be stabilized with each other, then the component has given us successful results.
Pins- Quantitative
We can test the pins through a stress test, and see that they won’t snap before 10 pounds. If it is still able to stabilize the upper and lower hooks without breaking the pins, then the component is successful.
Battery Holder - Qualitative
We can test the battery holder by how it is able to hold the battery and support the hooks. If it is able to support the battery on the hook without breaking it and still power the purifier, then the component is successful.
Initial Conditions: Floor with natural room obstacles, average room temperature, and the average amount of people in class as obstacles.
Materials: Computer, remote
Pass or Fail Criteria: What are your benchmarks? The component must be able to withstand a certain amount of pounds. The component must be durable and stable
Determine what would constitute a passing/failing mark or condition for this test. How should the device respond? How stable it is during movement. It should respond as stable as possible. How will you know if the event occurs during testing? If the purifier falls from the Roomba or stays on the Roomba.
Procedures:
1. Attach the Roomba top and side cover to the Roomba.
2. Attach the purifier halo to the purifier.
3. Attach the hooks to the Roomba and purifier and align them by the holes.
4. Put the pins in the holes to stabilize them.
5. Place the battery in the battery holder.
6. Set up the air quality analyzer in a place
7. Run the Roomba and purifier and test how it moves with the system in place while testing the purity of the air
Safety Considerations: Identify any potential dangers posed to people or property that could result from testing. The system could be a tripping hazard if not warned beforehand of the activation. Describe precautions needed to ensure the safety of the tester and others and to protect tools, equipment, fixtures, and the surrounding facility from damage. Advisement of the start of the system, googles, checking of the sensor to ensure that the Roomba will not hit anything.
Data: What type of data will the test produce? Quantitative and Qualitative. What unit of measure is being used? Pounds and stability
Data Collection Graph or Sheet: Determine how you are going to display this data. Create the actual form for gathering data. This may be supplied on a separate sheet of paper.

Instructor Comments and Signature: Seek input from your instructor. This is where your teacher will respond to your testing procedure. It may contain information that you will need to add to the final testing procedure before performing the actual test.
What is the purpose of testing your prototype?
To see if it will work and to fix any problems encountered.
What is the significance of test criteria?
It sets the basis of what to expect.
Is your test reliable? That is, can others repeat your test with the same results? Justify your answer.
Yes, if someone were to replicate our project, it will test the stability and reliability of their project.
Why is it important to eliminate bias in your test results?
So that the data isn't skewed and isn't one-sided.
Why does the test procedure need to be repeatable?
To factor out luck and weird environmental factors.
How do you know when you have enough step-by-step detail in your test procedure?
When the results show problems to be solved or if it allows for extensive success.
