Do you still use desk checking for non-trivial projects? If so, how much time do you typically spend on it? Also, do you evaluate all possible test cases?

Exploratory testing sessions can utilize the information gained during the desk checks and end up providing even more value. For most people, desk checking is relatively unproductive. One reason is that it is a completely undisciplined process. A second, what is desk checking and more important, reason is that it runs counter to a testing principle of Chapter 2—the principal that people are generally ineffective in testing their own programs. The reason is the synergistic effect of the walkthrough or inspection team.

If variable names consist of a number of words it is permissible to put a space between each word in the name so that the name fits better in the column by wrapping to the next line. E.g. the variable column heading discount Price could be used rather than the actual variable name discountPrice. “Dev-done” list was usually referenced before desk checks to help prepare for it better. I’ve also seen a desk check question list used to facilitate the meeting. I have as well seen the teams call an automatic desk check after 2 days of development on a work item.

Tools

Desk check can also serve as a quick way to get feedback from the product owner and end-users, or walkthrough the functionality to a separate user acceptance test team. Note that speed and team accountability is of utmost interest, so any “process” added could be an overhead. As the programmer writes the code/algorithm on his own, he can check if there is any issue or not, and fix the same before the project moves on to the later stages. Desk checking helps in locating the bugs or issues in an algorithm before the actual coding and ensures that the code performs as expected.

Our expert industry analysis and practical solutions help you make better buying decisions and get more from technology. A tester/analyst can raise bugs or problems during the session, or agree with the developer that acceptance criteria has been met . Other developers may also pitch in a test or two or probe to understand the system design even more.

Types of Defects in Software Testing

That’s why creating a seamless experience where people know what to expect and how to interact with a “new” space is a top priority for workplace teams. Only if you convince them that your code/design is likely to work, are you allowed https://globalcloudteam.com/ to move forward and actually add it to the project. This button displays the currently selected search type. When expanded it provides a list of search options that will switch the search inputs to match the current selection.

The following example shows desk checking involving selection using a non-linear nested IF-ELSEs. The following example shows desk checking involving selection using a linear nested IF-ELSEs. The following example shows desk checking involving selection using an IF-ELSE. The following example shows desk checking involving selection using an IF. The columns should be in alphabetical order on variable name with the variable name at the top of the column. As the algorithm is executed, the new values of the variables are put in the appropriate column.

Deskchecking and Debugging Output

If we choose to do so, a practice that can prove to be valuable is a desk check. Desk checks help to create shared accountability on quality. It is a technique for verifying the logic of an algorithm. It does not involve use of a computer, rather a person is responsible to carry out the desk check. The desk checker observes and analyses the logic behind the algorithm. It is the duty of the designer/programmer to make sure to have traversed through all possible paths of the logic and make use of every data set that is required.

Through desk checking, the developer gets validation against acceptance criteria from a tester’s and analyst’s (or other team member’s) perspective right away. These desk checks are commonly used for businesses, but are great for personal use as well. After all, keeping reliable records is just as important in personal finance as it is in business finance.

Desk Checking Algorithms Using Trace Tables

The following example shows desk checking involving subroutines. The following example shows desk checking involving sequence, selection and iteration . The following example shows desk checking involving sequence, executing instructions one after the other. Input-Output column displays the input value given by the user and the output result given by the program. The above algorithm displays the result as ‘a is greater’ and it is defined in the table as well. It reduces the time for evaluating the logic while implementing an algorithm to program as the programmer himself checks the logic or syntax errors before moving to later stages.

A test of an algorithm by a human , who runs through its operations in sequence to verify the result .

Test Early and Collaboratively with “Desk Checking”

We don’t have your requested question, but here is a suggested video that might help. Interactive resources you can assign in your digital classroom from TPT. Microprint Signature Line- Very small letters that can be read through a magnifying glass, but which appear to the unaided eye to be dashed or solid lines.

• Also, exploratory testing sessions definitely can take place within the development of the story, too.
• Each page has an in/out box with missing slots to be filled.
• Numbers, but these are necessary in a desk check to specify the line being executed.
• Your students are given a rule and asked to fill in the missing box by dragging the correct answer to the correct empty box.
• It is non-computerized process of checking the logic of an algorithm before its implementation as a program code.

Overall, a desk check takes place while the work is still in development. The developers are present and get feedback immediately if anything is missing. It could be challenging if your teams are in a big timezone gap. On these cases, it might be best to do local desk checks rather than involving the remote team. Consider changing your team structure to allow this to happen (e.g. consider Spotify’s “squad” model). Practically though — some bug fixes are too minor to even spend time to validate together (e.g. alignment issues, spelling mistakes).

Data-Driven Testing

Input-output field checks whether the input given by the user is logical and the output displayed by the code is performed according to the logic. Desk checking is similar to proofreading where all checking is being done with a pen and a paper and converting the lines of an algorithm to a table. A desk check focuses on the logic and value of the variables. This is quite different from a test plan, which does not focus on the internal workings and logic, and rather mostly focuses on inputs and outputs required by the application. A desk check is performed with the help of a table with columns for pseudo-code line number column, condition column, input/output column and a column for variables.
