<h2 id="h-what-is-test-file-upload">What is Test File Upload?​</h2>



Test File Upload in software testing refers to verifying the functionality of file upload features in a software application. This testing is typically performed by testers or developers (in the case of unit testing).



The QA testers must test the file upload functionality to ensure that users can successfully upload files (such as documents, images, videos, etc.) to the application and that the uploaded files are processed correctly.



Some examples of applications where we upload files include Amazon, Google Drive, and LinkedIn.



<h2 id="h-why-do-we-need-to-test-file-upload-functionality">Why do we need to Test File Upload Functionality?</h2>



File upload testing helps ensure that the file upload feature of an application works as intended, allowing users to submit files and ensuring that those files are handled properly.&nbsp;



This testing is crucial in applications that allow users to upload files, such as document sharing platforms, content management systems, and e-commerce applications.



Let me explain it in simple terms with an example scenario.



<h3 id="h-example-scenario">Example Scenario</h3>



Picture this: you&#8217;re using your favorite app or website, and you want to upload a file &#8211; perhaps a photo, a document, or even a video. It seems simple, right? Well, not quite.



Behind the scenes, a whole dance of processes is happening. The application needs to ensure that the file you&#8217;re uploading is the right type and size and that it won&#8217;t cause any hiccups in the system. It&#8217;s like the digital version of making sure your suitcase fits in the overhead compartment! 😜



<h2 id="h-prerequisites-of-test-file-upload">Prerequisites of Test File Upload</h2>



When conducting file upload testing, make sure to have certain prerequisites in place to ensure thorough and effective testing. Here are some of the key prerequisites for testing file uploads:



<ul><li>Create a dedicated <a href="https://testsigma.com/blog/test-environment/" target="_blank" rel="noreferrer noopener">testing environment</a> that closely mimics the production environment.</li><li>Prepare a set of test files with varying sizes, formats, and types. These files should cover a range of scenarios, including small and large files, different file types (For example, images and documents), and potential edge cases.</li><li>Understand and document the maximum file size that the application supports for uploads. This information is crucial for <a href="https://testsigma.com/guides/test-scenario/" target="_blank" rel="noreferrer noopener">testing scenarios</a> involving files of different sizes.</li><li>Select a test automation platform to automate file upload testing to eliminate manual errors and reduce testing time.</li></ul>

</div>



<ul><li>Determine which file types the application allows for upload. Some applications may restrict certain file formats (For example, .exe files) due to security concerns.</li><li>Test under various network conditions to simulate real-world scenarios. This may include testing on different types of connections (For example, high-speed, 3G, and slow networks) to assess how the application handles uploads under different circumstances.</li></ul>



By ensuring these prerequisites are met, testers can conduct comprehensive and effective file upload testing, which helps identify and address any issues related to this critical functionality in an application.



<h2 id="h-how-to-test-a-file-upload-functionality-manually-and-automation">How To Test a File Upload Functionality &#8211; Manually And Automation?</h2>



You can upload both manually and using automation. Let&#8217;s discuss both ways to understand the pros and cons of each method. That way, you can easily identify the best way to test file uploads.



<h3 id="h-manual-testing">Manual Testing</h3>



The simplest way to do file upload testing is using the manual approach.&nbsp;



<ol><li>Open the web page in the browser where you want to test file upload.</li><li>Write test cases for every scenario and prepare test data for those tests.</li><li>Execute each test case you have created and mark your observations in a sheet.</li><li>To make sure we have tested different file formats, upload and test different files with different formats (For example, PNG, PDF, JPG, Docx, MP4, etc.</li><li>Verify that only the correct extensions pass the test cases. To do so, you should perform both positive and<a href="https://testsigma.com/blog/negative-testing/" target="_blank" rel="noreferrer noopener"> negative testing</a>. That is, you need to use both valid and invalid data for testing. </li></ol>



Let&#8217;s take LinkedIn as an example. A professional networking platform that we all use in our day-to-day lives.&nbsp;



<div class="wp-block-image"><figure class="aligncenter is-resized"><img loading="lazy" src="https://lh7-us.googleusercontent.com/0SKMBzBBWh2eexfpc9wAe3Xr7a58XKmoqPK_28sjyLRkrI__wMQ6OcmO2BRPLgzOcX8l23daICHUgeOlxHkSsorzJu3ZitJiLnAjIusqDnk_4kFbt0gvjC3fu05Fscv4KyEzTcnxdQfJqGvvuiNyHuE" alt="LinkedIn as an example for Testing File Upload" width="729" height="483" /></figure></div>



Most of us would have opted for LinkedIn jobs while looking for new opportunities. LinkedIn&#8217;s Easy Apply permits users to upload their resume only in a few formats (PDF, DOC, DOCX). That is, when you try uploading other formats, LinkedIn will not permit that action. To verify this functionality works correctly, testers have to perform file upload testing using various and invalid inputs as follows,



<ul><li>Valid data &#8211; PDF, DOC, DOCX&nbsp;</li><li>Invalid data &#8211; JPG, PNG, XLS, etc.</li></ul>



This manual testing approach might look very simple in the beginning, but the number of test cases can increase up to 100 or more when you expand the test scenarios. In the long run, this will increase the project budget and buggy software, as repetitive manual testing can be error-prone. Alternatively, automated testing is the best option to solve this issue.

<h2 id="h-what-is-agile">What is Agile?</h2>



Agile is a project management methodology grounded in the values and principles of the Agile Manifesto. It is a flexible and iterative approach that emphasizes continuously adapting to changing requirements to deliver value to the customer.&nbsp;



Agile teams collaborate and communicate openly to deliver functional software within short timeframes. Customer satisfaction is prioritized, and the teams aim to produce high-quality software that meets the customers&#8217; needs.&nbsp;



To all these, additionally, Agile values self-organizing teams that take ownership and responsibility for their work, continuously improving their processes and practices.



For example,



Let&#8217;s say a software development team is tasked with building a new e-commerce website for a client. Using Agile project management, the team would break down the project into smaller, more manageable tasks or &#8220;user stories&#8221; that can be completed within a two-week sprint.&nbsp;



During the <a href="https://www.atlassian.com/agile/scrum/sprint-planning" target="_blank" rel="noreferrer noopener">sprint planning</a> meeting, the team would prioritize the user stories based on the client&#8217;s needs and the estimated effort required to complete each task.&nbsp;



The team would then work together throughout the sprint to complete the tasks, holding daily stand-up meetings to discuss progress, challenges, and any adjustments needed to the plan.&nbsp;



At the end of the sprint, the team would present the completed user stories to the client for review and feedback. The client would then provide feedback, and the team would use that feedback to adjust the plan for the next sprint.&nbsp;



This iterative process continues until the project is complete, with the team continuously adapting to changing requirements and delivering value to the client at each step.

Software Walkthrough | What it is, How it works & Examples

Control flow graph(CFG) in software testing is the key to unlocking the hidden pathways of a program&#8217;s logic, allowing testers to uncover potential pitfalls and ensure robust functionality. Just like an explorer relies on a map to chart their course through unknown territory, a tester leans on the CFG to guide them through the twists and turns of code execution.&nbsp;



Just as a well-drawn map can make a trip more enjoyable and less prone to wrong turns, a well-constructed CFG simplifies the testing process, making it more efficient and effective.&nbsp;



Not just that, CFG has more to do with software testing. This blog will discuss everything about control flow graphs and control flow testing in software testing.



Before we get into how control flow testing works, let&#8217;s see what control flow graph is and how control flow graph plays an important role in software testing.

<h2 id="h-what-is-a-control-flow-graph">What is a Control Flow Graph?</h2>



Control Flow Graph is a visual representation of a program&#8217;s control flow, showing how the program progresses through various statements and decision points.



The control flow graph was developed by Frances E. Allen, inspired by Reese T. Prosser&#8217;s use of boolean connectivity matrices for flow analysis.



<h2 id="h-what-is-control-flow-testing">What is Control Flow Testing?</h2>



Control flow testing is a software testing technique that helps ensure that the different paths a program can take are tested. It is a white-box testing technique. The goal of control flow testing is to verify that all possible execution paths of a program behave as expected.



Need more clarity? Let me explain it in a way that is as easy as ABC.&nbsp;



Imagine you have a computer program with a set of instructions for the computer to follow. Sometimes, the program can go in different ways based on certain conditions (like if-else statements in code).



Now, the testers will test all these different paths to ensure the program works correctly. Simply put, it is like checking that different roads on a map lead to the right destination.



<h3 id="h-how-control-flow-testing-done">How Control Flow Testing Done?</h3>



Control flow testing is usually performed using a control flow graph (CFG), which is a graphical representation of the flow of a program.&nbsp;



The CFG shows the different nodes in the program, such as statements, branches, and loops, and the edges between them.



The software tester will start by creating CFG, which will help them identify all the possible execution paths of a program. Then, the tester can create test cases to cover each path.



<h2 id="h-purpose-of-control-flow-testing">Purpose of Control Flow Testing</h2>



A <a href="https://www.scribd.com/presentation/193784605/Controlflow-Testing">study</a> states that control flow testing helps detect 50% of bugs during unit testing. And that is about 33% of all bugs.



But, control flow testing cannot find all bugs in a program. For example, it can not find interface issues.



Here are some examples of control flow testing,



<ul><li>Testing all branches of an if statement.</li><li>Testing all cases of a switch statement.</li><li>Checking all possible iterations of a loop.</li><li>Testing the error handling.</li><li>Testing the performance of the application for different inputs.</li></ul>



By testing all possible paths through a program, testers can ensure that the program is high quality and meets user requirements.



<h2 id="h-control-testing-example">Control Testing Example</h2>



Let&#8217;s look at an example program in Java and see how control flow testing works.



<div class="wp-block-image"><figure class="aligncenter"><img src="https://lh7-us.googleusercontent.com/PL_I_YgR50mqW9Oz7mb6qqUlL8h_gkt7giKLQ_ffROJyAtlmROUVBuzYWxPvEzUTjq9SNDH3xLQAMzot-K8ZOBA6-4DgCZRmKAQcOXNRkm4pQgXUWwgEHb6sN7IHsMLpQDkxxbCq_PJnR-2XKxyl8cE" alt="Control Flow Testing Example"/></figure></div>



Control flow testing will help testers test all the possible paths the above program can take. That way, they can make sure the program works as expected with any path.



<h2 id="h-uses-of-control-flow-testing">Uses of Control Flow Testing</h2>



Control flow testing, a type of white box testing, involves analyzing program code by executing test cases. Another approach involves executing data flow.



Here are the key uses of control flow testing:



<ul><li>Unit Testing &#8211; Control flow testing is mainly in <a href="https://testsigma.com/blog/unit-testing/" target="_blank" rel="noreferrer noopener">unit testing</a>. It aims to identify the different paths of execution in the code. Test cases are then created based on these paths and executed.</li></ul>



<ul><li>Control Flow Graphs &#8211; This testing involves creating control flow graphs. These graphs provide a visual representation of how the program flows. By analyzing these paths, testers will be able to write various test cases.</li></ul>



<ul><li>High Test Coverage &#8211; When testing with CFGs, every node and edge in the graph is covered. Thus, it helps achieve high test coverage.</li></ul>



<h2 id="h-notation-of-control-flow-testing">Notation of Control Flow Testing</h2>



Control flow testing consists of four nodes, namely,



<ol><li>Node</li><li>Edge</li><li>Decision Node</li><li>Junction node</li></ol>



<h3 id="h-node">Node</h3>



A node represents a basic block of code. It is a section of code that runs from start to end. The nodes show the order of procedure in a program. They help testers to identify what step comes next, making it easy to understand the sequence of actions.



<h3 id="h-edge">Edge</h3>



An edge represents a possible transition or flow of control from one node to another.



<h3 id="h-decision-node">Decision Node</h3>



A decision node, also known as a conditional node, represents a point in the program where a decision is made based on a condition (e.g., an if-else statement).



<h3 id="h-junction-node">Junction Node</h3>



A junction node is a point in the program where at least three nodes meet. It is used to represent points where multiple branches merge back into a single path or split into multiple paths. Simply put, junction nodes are where different nodes lead to one node.



<div class="wp-block-image"><figure class="aligncenter"><img src="https://lh7-us.googleusercontent.com/v-yrHnlBdyx8ISC-yIRSQ6eLt3AACyUJmAeuBKcc2eNMjBYatI5KMyLdwOcG9bcmyhyrPe97hiijOa_QrTiFknwQ4GL6dm0Y9E-rPHBt4EtUYkLXVrNooy-jJEcmxU4Sdh6B413cxKgMEn3ggpA9X18" alt="Notations of Control Flow Graph"/></figure></div>



<h3 id="h-control-flow-testing-notations-example">Control Flow Testing Notations &#8211; Example</h3>



Let&#8217;s understand these notations using a simple program. The below program checks if a person is eligible to vote or not.



<div class="wp-block-image"><figure class="aligncenter"><img src="https://lh7-us.googleusercontent.com/d6nSmiiPu8O-wbsUToHk-qhNnBDd_L3kjkE_Pt8FLrR4j-T4b_ffjNAnO1sVC2gvd0dEXRAoLS5jkvohpD5vkC-ZXnCYEDYR_B4lUbeSiHOGhxWLg3WYInrU7XRtEI7ODNyUj72tU14QVsBaxUrUPxo" alt="Control flow testing in software testing"/></figure></div>



What will this program do?



Simple, it takes two paths, as follows,



<ul><li>If x is greater than or equal to 18, it prints the message &#8220;You are eligible to vote.&#8221;</li><li>Else, when x is less than 18, it prints the message &#8220;You aren&#8217;t eligible to vote.&#8221;</li></ul>



Here, the input value &#8216;x&#8217; denotes the age.



<h3 id="h-sample-control-flow-graph">Sample Control Flow Graph</h3>



Now, the control flow graph for the above program will be as follows,



<div class="wp-block-image"><figure class="aligncenter"><img src="https://lh7-us.googleusercontent.com/SWz4jNIu4yJ-htpSWpHLZZH0rSSnTuBUxh4-c4khbfTawpQ7ND62YCDalnlTGFnWgf5G1Rnfw1xGl-pqANiGZSP2kLYm-kmB8KFHCyAaPAjSorFyBfb2XSlyXU_JYdw2rd0ffboONfDnB08CgWgCing" alt="Control Flow Graph"/></figure></div>



Let&#8217;s see which are what notations.



<ul><li>Nodes &#8211; Start, Age, Eligible, Not Eligible, Stop</li><li>Decision node &#8211; x&gt;=18</li><li>The last node that leads to the stop is the Junction node.</li><li>Edge &#8211; All the direction arrows that connect the nodes</li></ul>



<h2 id="h-control-flow-testing-process">Control Flow Testing Process</h2>



The control flow testing process involves the following steps,



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/aUNjJltNeUEgZUA9wXB-qPxYfkpJfqOLTWHUplWpDdRP8KWjPipNWeVfdBcf0QjPZDsIG22l5PnoovA7y2dyZbI2DBGnNRrPE9qdz4XDwvCMeRPCXyWYJEhofFOOTf85WDaXxDABHpEZRpJjKXObnZo" alt="Control flow testing process"/></figure>



<h3 id="h-1-control-flow-graph-creation">1. Control Flow Graph Creation</h3>



Start by creating a control flow graph, a visual representation of how the program runs based on the source code. It can be created manually or with a software.



<h3 id="h-2-coverage-target">2. Coverage Target</h3>



A coverage target is defined over the CFG, which includes nodes, paths, edges, branches, etc. Here, testers will decide what part of the graph has to be tested.



<h3 id="h-3-test-case-creation">3. Test Case Creation</h3>



Develop specific test scenarios and test cases based on the control flow graph to cover the designed coverage target.



<h3 id="h-4-test-case-execution">4. Test Case Execution</h3>



Now, execute the test cases that were created to target specific parts of the program.



<h3 id="h-5-analysis">5. Analysis</h3>



Analyze the test results and find out if the program behaves as expected or not.
