Answer: The three types of testing in the computing field are unit testing, integration testing and system testing .The following testing are mentioned in working order of as follows:-

Unit testing -It is the testing that is used for the evaluation of the task performed by small unit code of the software system.It has the main focus on the function testing of the codes individually.

Integration testing:- It checks the modules that are combined togather are working in the required manner or not. It can evaluate almost whole system through it's testing . Top-down integration and bottom-up integration are the two methods for integration testing.

System Testing:- system testing is the evaluation that covers the complete system by functional and non-functional test.The parameters tested in this testing are usability, reliability, scalability,security etc.

Answer and explanation:

There are four (4) main types of testing and the order in which they are performed is the following:

1) Unit Testing

2) Integration Testing

3) System Testing

4) Acceptance Testing

Unit testing is usually made by software developers individually. Modular codes are used so it implies they will be more reliable easier to be reused. Integration testing implies combining the results of the testing in unit testing. The goal of this testing is to measure how well the system works by interacting with others. System testing comes third after evaluating all the units as only one- At this level, the system is evaluated to find out if it meets the requirements established. Finally, acceptance testing takes place before the software will be sent to the final users.

{

meters_tf.setText(df.format(meters));

inch_tf.setText(df.format(inches));

yards_tf.setText(df.format(yards));

}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.
