Testing mobile phone number fields sounds simple and it is, but it can be complex if multiple locations (countries) are supported. Phone number formats are often different depending on the country or nation. Supported locations make a difference when testing phone number formats, number entry patterns, and error messaging based on type and location.



<a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">Test cases</a> for mobile numbers vary based on a user&#8217;s global location (country). The application design or requirements are likely based on a specific location or multiple locations. If your documentation doesn’t specify, ask the product manager, designer, or developer for all supported locations to test against.&nbsp;

<h2 class="wp-block-heading" id="h-what-is-a-mobile-number-field">What is a Mobile Number Field</h2>



A mobile number field is a representation of a user’s phone number. The format, style, and characters accepted change based on specific application requirements and whether the application is using the E.164 (The International Public Telecommunication Numbering Plan) standard and/or the NANP (North American Numbering Plan).&nbsp;



Test cases for mobile phones need to consider both the <a href="https://learn.microsoft.com/en-us/globalization/locale/telephone-numbers" target="_blank" rel="noreferrer noopener">E.164 and NANP</a> if the application is sold globally. The E.164 sets a number limit of 15 characters including a three-digit country code. All nations using the NANP have a country code of 1 and a ten-digit number character limit. The first set of numbers represent the country code followed by the regional code and then the phone number.&nbsp;

Phone number test cases are assumed in this blog to support both the E.164 and the NANP. We’ve listed the valid test cases first, followed by a few suggested tests for negative or error messaging testing.&nbsp;



Mobile number test cases for functional testing include:



<ul class="wp-block-list"><li>Verify the mobile phone field exists and accepts data entry.</li><li>Enter a valid phone format for a specific location (US and other nations)<ul><li>Verify the user must include the country or area code. </li><li>Verify NANP standards apply to the United States, Canada, and Jamaica.</li><li>Verify E-164 standards apply to all other countries. </li><li>Verify any countries that don’t follow the E-164 standard. </li></ul></li><li>Copy and paste a valid <a href="https://www.cloudtalk.io/geographic-numbers-pricing/" target="_blank" rel="noreferrer noopener">geographic phone number</a> from a different form field.</li><li>If the mobile number field is required, verify there is a visual indicator to let the user know valid data must be entered.</li><li>Depending on the field design, including special characters to separate numbers like parentheses and dashes:<ul><li>Example: (202) 444-9876.</li></ul></li><li>If the application uses drop down selectors, select a valid country and enter a valid number for that location.</li><li>Select the country code dropdown and view the list of supported country formats. <ul><li>Verify the list is in alphabetical order for easier viewing. </li><li>Verify the number selected displays in the field as expected. </li></ul></li><li>Test that the tab order stops in the mobile phone field and allows the user to enter a valid number. </li><li>View the field and check that it aligns as expected with other fields and within a group. </li></ul>



Mobile number negative test cases include:



<ul class="wp-block-list"><li>Exceeding the allowed character limit.</li><li>Entering a correct country or area code with an invalid number for that location.</li><li>Enter an invalid country or area code with a valid number.</li><li>Enter in numeric characters with alpha characters.<ul><li>Example: 1404abc9877.</li></ul></li><li>Enter a valid country code and a phone number that’s one or more numbers to short for the selected location.&nbsp;</li><li>Enter a valid country code and a phone number that exceeds the character limit for the location.</li><li>Enter a valid phone number but include various special characters (!@#$%^&amp;*())<ul><li>Example: 1720(3457)</li><li>Example: 005588#</li></ul></li><li>Enter as many characters as the field allows up to 100.&nbsp;<ul><li>This test sounds silly, but it’s a good way to verify that the application is coded to avoid mass data entry.&nbsp;</li></ul></li><li>Enter a scripted SQL or HTML coded string.&nbsp;<ul><li>This test checks that the field does not execute code.&nbsp;</li><li>Example: 18084560&lt;bold&gt;97&lt;/bold&gt;</li></ul></li><li>If the mobile phone field is required, try to enter and save information without filling it in.&nbsp;<ul><li>Optionally, try filling the mobile phone field with invalid data or partial valid numbers.&nbsp;</li></ul></li></ul>



For each negative test case, verify an error message is triggered indicating the error so the user can understand the problem and make corrections. Remember it’s good practice to have a peer or developer to <a href="https://testsigma.com/blog/test-case-review/" target="_blank" rel="noreferrer noopener">review test cases</a> when possible. The better the test case, the better the test coverage.&nbsp;



<h2 class="wp-block-heading" id="manual-and-automated">Manual and Automated&nbsp;</h2>



The table below gives you an example of typical test scenarios for creating manual test cases for mobile numbers:



<figure class="wp-block-table"><table><tbody><tr><td>Test ID</td><td>Description</td><td>Expected Result</td></tr><tr><td>1</td><td>Verify the mobile phone field exists and accepts data entry.</td><td>Confirm the field exists and is enabled to allow users to enter data.&nbsp;</td></tr><tr><td>2</td><td>Enter a valid phone format for each specific location format supported.&nbsp;</td><td>Verify each supported format allows users to enter a valid phone number into the field without resulting in an error.&nbsp;</td></tr><tr><td>3</td><td>If the application uses drop down selectors, select a valid country and enter a valid number for that location.</td><td>Select each drop down option in turn and verify it matches with a valid phone number.&nbsp;Confirm no error messages are generated.&nbsp;</td></tr><tr><td>4</td><td>Test that the tab order stops in the mobile phone field and allows the user to enter a valid number.</td><td>Tab through the form or page fields and verify it lands as expected in the mobile phone field.&nbsp;Enter a valid number and verify no errors are generated.&nbsp;</td></tr></tbody></table></figure>



The above table is a sampling only. You can write as many test cases as you need to cover requirements and standard functionality within your application. Additionally, you can create test cases in a design that fits with your development and QA team.&nbsp;



Creating test cases for mobile phones are excellent candidates for test automation. For creating test cases for mobile phones consider using Low code test automation platform, Testsigma and organize your tests in the following modular flow as below:



<figure class="wp-block-table"><table><tbody><tr><td>Test ID</td><td>Description</td><td>Expected Result</td></tr><tr><td>1</td><td>Click into the mobile phone field.&nbsp;Enter test data for a valid US based phone number: 1+(309)665-9087</td><td>Validate the correct phone number displays and is saved without error.&nbsp;</td></tr><tr><td>2</td><td>Click into the mobile phone field. Enter test data for a valid UK phone number: +44&nbsp; 20 7123 4567 NOTE: Consider using Testsigma’s automation tool to run through all valid formats in a single test. Add validation points for each valid type.&nbsp;</td><td>Validate the correct phone number displays and is saved without error.&nbsp;</td></tr><tr><td>3</td><td>Create a test script that enters all required fields with valid data including the mobile phone field.&nbsp; Click the Save/Submit button when all fields are filled.&nbsp;</td><td>Verify for each supported format type the application enters valid data into the database and saves/submits without error.&nbsp;</td></tr><tr><td>4</td><td>In the application form, enter valid phone numbers for each supported location type but leave off at least one digit.</td><td>Validate each supported format type generates the correct error message.&nbsp; Enter a validation point for each format’s specific error message.&nbsp;</td></tr></tbody></table></figure>



Note, the above is a sample. You can learn how to use Testsigma to create automated scripts for each manual functional test &#8211; both positive and negative. Remember to create the relevant test data and ensure the data can be reset or refreshed for future automated test execution runs.&nbsp;

<h2 class="wp-block-heading" id="summary">Summary</h2>



Phone number test cases at first seem quite easy and simple. However, once you start testing for all supported formats, there is a great deal of testing to cover. Due to mobile phone number test cases being repetitive, consider using Testsigma to create automated test scripts.&nbsp;



The first step for either automated or manual testing is understanding the relevant requirements and creating a thorough set of test data.&nbsp;



Testers don’t have the luxury of time to continually look up valid phone numbers for every location or country/region. Save your testing time by creating a full set of valid numbers or generating them using a test automation tool. Ensure you have fully covered testing in the field using both positive, negative, and error messaging test cases.&nbsp;

<h2 class="wp-block-heading" id="h-what-is-grey-box-testing">What is Grey Box Testing?</h2>



Grey box testing, which is also called Gray box testing, is a way to debug software and find out if there are any vulnerabilities. In this type of testing, the tester needs to learn more about how the part they&#8217;re testing works.&nbsp;



This differs from black box testing, where the tester doesn&#8217;t know anything, and white box testing, where the tester knows everything.



In these tests, the tester usually knows what&#8217;s inside an application but not exactly how everything works together. This ensures that testing is like what real attackers and users would do.



Grey box testing is best for checking web applications, testing how things work together, looking at things across different systems, testing business ideas, and checking how secure something is.&nbsp;



Testers and developers must stay separate to ensure fair test results when doing this kind of testing.



As you already know, Grey box testing combines black box and white box testing. You can automate entire black box testing using <a href="https://testsigma.com" target="_blank" rel="noreferrer noopener">automation testing tools</a> like Testsigma.&nbsp;

<h2 class="wp-block-heading" id="h-objectives-of-grey-box-testing">Objectives of Grey Box Testing</h2>



Grey box testing is one kind of <a data-wpil="url" data-wpil="url" data-wpil="url" data-wpil="url" href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a>. Here we can check the objectives of Grey Box Testing:



<ul class="wp-block-list"><li>Unify strengths of Black Box &amp; White Box testing: Combine the user-centric perspective of Black Box with the internal knowledge of White Box to uncover diverse defects. </li><li>Improve overall software quality: Identify a wider range of bugs, including logic errors, data manipulation issues, and security vulnerabilities, leading to a more robust product. </li><li>Optimize testing efficiency: Reduce redundant testing by leveraging Black Box and White Box techniques, saving time and resources. </li><li>Enhance tester-developer collaboration: Bridge the gap between development and testing teams by fostering a shared understanding of the software&#8217;s internal workings and user experience. </li><li>Focus on user perspective: Ensure the software behaves as expected from the user&#8217;s standpoint, not just from the developer&#8217;s perspective.</li></ul>



<h2 class="wp-block-heading" id="h-what-is-an-example-of-grey-box-testing">What is an Example of Grey Box Testing?</h2>



Picture this &#8211; you&#8217;re trying out an online store&#8217;s checkout process.&nbsp;



To test it out, you&#8217;d add items, put in different addresses, and double-check if you got a confirmation message. But if you had some knowledge about the backend database, you could do a &#8220;grey box&#8221; test.&nbsp;



What&#8217;s that? It&#8217;s when you push the limits and try to trigger errors or uncover issues with data handling. It&#8217;s like being an investigator and finding out what&#8217;s going on behind the scenes.



<h2 class="wp-block-heading" id="h-grey-box-testing-techniques">Grey Box Testing Techniques</h2>



Gray Box Testing Techniques:



<ul class="wp-block-list"><li>Boundary Value Analysis: Test extreme values (minimum, maximum, invalid) for inputs and outputs to discover edge case bugs. </li><li>Equivalence Partitioning: Divide input data into categories with similar characteristics and test one representative value from each, ensuring coverage of different scenarios.</li><li>Error Guessing: Leverage knowledge of common software errors to design test cases that target specific vulnerabilities. </li><li><a href="https://testsigma.com/guides/api-testing/" target="_blank" rel="noreferrer noopener">API Testing</a>: Utilize knowledge of API specifications and data structures to test data flow and functionality within the software&#8217;s internal components. </li><li>State Transition Testing: Test the software&#8217;s behavior as it transitions between different states (e.g., login, logout, edit, save) to identify state-related bugs. </li><li>Security Testing: Combine knowledge of best practices and potential attack vectors with user-based testing to uncover security vulnerabilities.</li></ul>



<h2 class="wp-block-heading" id="h-advantages-disadvantages-of-grey-box-testing">Advantages &amp; Disadvantages of Grey Box Testing</h2>

<h2 class="wp-block-heading" id="h-the-grey-box-testing-process">The Grey Box Testing Process</h2>



Grey box testers usually have access to some basic information about the system under test, such as design documents, flowcharts, or source code snippets.



Here are the steps involved in the Grey Box Testing Process:



1. Requirement Analysis: In this step, the testing team analyzes the requirements of the software application to be tested. They also gather information about the system architecture and its components.



2. <a href="https://testsigma.com/guides/test-planning/" target="_blank" rel="noreferrer noopener">Test Planning</a>: After analyzing the requirements, the team prepares a test plan that outlines the testing objectives, scope, and approach. They also identify the test cases to be executed, the testing environment, and the tools required for testing.



3. Test Case Design: In this step, the test cases are designed based on the requirements and the partial knowledge of the <a href="https://en.wikipedia.org/wiki/Systems_architecture" target="_blank" rel="noreferrer noopener">system architecture</a>. The test cases are designed to validate the functionality of the software application.



4. Test Case Execution: The designed test cases are executed in the testing environment using the identified tools. The test results are documented, and defects are reported to the development team for fixing.



5. Defect Retesting: After the development team fixes the defects, the testing team performs defect retesting to ensure that the defects are resolved and do not recur.



6. Regression Testing: Regression testing is performed to ensure that the changes made to the software application do not affect the existing functionality.



7. <a href="https://testsigma.com/blog/test-closure-report/" target="_blank" rel="noreferrer noopener">Test Closure</a>: After all the test cases are executed, the testing team prepares a test closure report summarizing the testing activities, including the defects found and resolved. The report is shared with the stakeholders, and the testing process is closed.&nbsp;
