Desk checking enables developers to proceed in a very systematic manner, in terms of coding. This technique eliminates the chances of erroneous code as proper review is done to analyse the problem and therefore offer the best solution for a given problem. Desk checking is an informal manual test that programmers can use to verify coding and algorithm logic before a program launch. Pseudo code is tested by passing the sample test values for the variables or conditions used in the code to analyze their correctness. Normally portrait page layout would be used for the desk check, however if the table is too wide, landscape layout may be used.

The Origin of ‘Checking In’
Desk checking is also known as hand tracing that implies the technique of testing an algorithm’s logic and input/output variables by the programmer. Desk check is performed manually by walking through every line in a pseudo-code to identify the bugs in logic and to ensure if the algorithm works as definition of desk checking intended. It is performed on an algorithm code using tables with columns as line number, value of variables, conditions if applicable, input-output and result expected. Each line of a pseudo code is assigned a number and this line number is the first field in the table designed for desk check.
Developers may desk check their code before releasing a software program to make sure the algorithms are functioning efficiently and correctly. While desk checking is useful for uncovering logic errors and other issues within a program’s source code, it is time-consuming and subject to human error. Therefore, an IDE or debugging tool is better suited for detecting small problems, such as syntax errors. The desk checker carefully follows the algorithm being careful to rigidly adhere to the logic specified. 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.

The condition column helps in the showing the working when evaluating the conditions. The input/output column helps in showing the inputs and outputs, and helps in evaluating the input received by the user and the output displayed by the logic. The column for variables helps in evaluating the calculations using variables. The programmer/designer/tester starts with some possible inputs and walks through the algorithm line by line. The lines are assigned line numbers and proceed with each one taking into account the change in values for variables.
Another benefit of a desk check is that it confirms to the programmer/designer that the algorithm performs as intended. Debugging software as it is being developed is a form of desk checking. The developer sets breakpoints or checks the output from the model to verify that it …
Translations of check-in desk
Now that we have a better sense of the meaning and origin of ‘checking in,’ let’s look at some of the practical ways you might use the phrase in a sentence. Now that you understand the various meanings of ‘checking in’ and ‘check in,’ you can confidently use these phrases when writing and speaking. Perhaps the most common usage of the phrase ‘checking in’ in a casual conversation has to do with connecting with another person in order to talk or exchange a status update.
A Desk Check concentrates on the value of variables and the logic i.e. what is the value of variable xafter statement n; what is the next statement to be executed? A Test Plan focuses on the values of inputs and outputs required to test a program without concern for the internal workings i.e. are the results correct for the inputs?. The term “desk checking” refers to the manual approach of reviewing source code , rather than running it through a debugger or another automated process. In some cases, a programmer may even use a pencil and paper to record the process and output of functions within a program. For example, the developer may track the value of one or more variables in a function from beginning to end.

Program execution loops from the ENDWHILE line, back to the WHILE line. More examples An angry passenger was swearing at the poor girl behind the check-in desk. Desk checks have been carried out on the Article 8 declarations received during the second half of 2002. To grovel over hardcopy of source code, mentally simulating the control flow; a method of catching bugs. No longer common practice in this age of on-screen editing, fast compiles, and sophisticated debuggers – though some maintain stoutly that it ought to be.
Although a useful technique for spotting errors, modern debugging applications and tools have made desk checks less relevant and not as essential as they previously were. The use of the phrases to ‘check in’ or ‘check out’ in relation to a hotel and other things, such as library books, dates back to at least 1909. ‘Check up,’ on the other hand, which is related to the meaning of ‘checking in’ refers to communicating for a status update, dates back to 1883. Desk checking is the process of manually reviewing the source code of a program. It involves reading through the functions within the code and manually testing them, often with multiple input values.
