It helps to identify the defects at the edges of the given input ranges. For example : Password must in 6-10 characters<br> 5 -- Fail<br> 6 -- Pass<br> 7 -- Pass<br> 9 -- Pass<br> 10 -- Pass<br> 11 -- Fail</p> <blockquote> <h4> Equivalence Partitioning </h4> </blockquote> <p><code>Equivalence Partitioning</code> In this technique,divides the input data into the valid and invalid partitions. For Example Age limit of 18 to 60<br> Below 18 age -- Invalid<br> 18 to 60 -- Valid<br> Above 60 -- Invalid</p> <p>16 -- Fail<br> 22 -- Pass<br> 61 -- Fail</p> <blockquote> <h4> Decision Table Testing </h4> </blockquote> <p><code>Decision Table Testing</code> In this techniques, used a table format to outline of various input combination and their expected outputs, ensure the all the cases are covered.</p> <p>Rule : 1<br> If the Email ID and Password are correct, the mail will logged in</p> <p>Rule : 2<br> If the Email ID is correct and Password is wrong, Error message populated.</p> <p>Rule : 3<br> If the Email ID is wrong and Password is correct, Error message populated</p> <p>Rule : 4<br> If the Email ID and Password are wrong, Error message populated.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fb38qt7y44q0i7o43sjzf.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fb38qt7y44q0i7o43sjzf.png" alt=" " width="800" height="152"></a></p> <blockquote> <h4> The Future of Manual Testing in the Age of <strong>AI</strong> </h4> </blockquote> <p>In most of the companies are using the automation testing for identifying the bugs quickly, testing time reduced and the needed the minimum number of tester. However there are some test cases which can't replaced by automation testing. The AI techniques and automated tools can't reproduced the logical thinking, Innovation, Objective analysis of human.<br> Automated tools executed the code level performing based on the predefined logic. Manual testing techniques is not disappearing. AI techniques can be performed effective for repeat tasks, complexity task, comparing or analyzing the large dataset and the experienced tester have ensure the quality of product</p> beginners testing tutorial
