What is Exploratory Testing? Importance and Steps

There is no need to strictly follow those parameters but they act as a guideline. However, scripted testing is a time-intensive methodology; if the steps are too specific, they can become invalid or irrelevant with product evolution. Software testing consists of numerous practices and approaches that help secure overall accurate results through all stages of the testing phase. Most of these approaches are implemented by following certain steps based on pre-planned test cases and assessing the actual results against what is expected. Regardless of how much time is spent testing using rigorous manual and automated test scripts, errors still manage to make their way into every release.

scripted testing vs exploratory testing

Such adaptability will not be available in scripted testing as you would have to go through with all the steps and tests even if there are no bugs. Yes, it will be very important to follow the scripted testing approach when you are testing critical modules or apps. In the late 90s and early ‘aughts, test heavyweight James Bach birthed the idea of defect detection through exploration, rather than scripted test cases. Exploratory testing , he argued, would allow a tester to work within a larger sphere and increase defect detection. Exploratory testing is a manual method of exploring an app without test scripts or predetermined input definitions.

This is done by treating learning, test design, test execution, and test result evaluation as mutually supportive activities that run in parallel throughout the project. Exploratory testing is done with a view that software is bound to have defects in it. The tester has to somehow identify these defects using any possible combination of techniques that forces the software to behave in an undesirable manner. That approach is termed as destructive testing; where the original aim is to destroy the system by specific steps and then check if the system can withstand these destructive techniques.

scripted testing vs exploratory testing

Many people have asked me which is better in software testing; exploratory vs scripted. Exploratory tests are carried out ‘on the go’ and allow the tester to take steps which a user might take but not the ones the script tells. Having no restraints it shows how the product might be used ‘in the wild’. A common thing for the creators of the product is to miss some unexpected details. Scripted testing includes test cases and following them strictly. This methodology can simply lead a tester to a desired result but many bugs users might face can fall out of scope.

Test Sessions

While exploratory testing is more time consuming and costly than other forms of testing, it tends to uncover more bugs – and especially more complex defects – than scripted testing. In the early life of software, exploratory testing is the most effective to determine how it will perform in actual usage. The tester should have knowledge of who the product is for and what is it intended to be used for. In scripted testing, the test cases are designed first and then they will proceed to test execution will proceed.

By setting fixed time periods during which certain activity should be accomplished, testers can ensure that the process remains efficient. Typically, two testers will work together uninterrupted for a period of 90 minutes or more. When creating a test charter, testers should determine what should be tested and how best to test it. The charter should also document the starting point for https://globalcloudteam.com/ testing and outline how users will interact with the application. For defects that should be immediately obvious, such as a missing button in the UI, exploratory testing discovers 29% more vs. scripted. I like that you’re working to improve practice of manual testing, but IMO in your zeal you’ve lost sight of the fact that measuring product quality is much more than just finding bugs.

Comparison Table: Exploratory vs Scripted Testing

Project owners can get insights that were not possible to get with scripted tests. All test scripts and test cases are designed and reviewed in advance. When the project demands early rehearsals or when a new tester has joined a project that is already in full action.

scripted testing vs exploratory testing

So when you find something you didn’t expect when you begin your tests, you can redefine your goals based on the new findings and stay focused on them. But when it comes to scripted testing, finding something unexpected itself is not very likely as the approach increases the tendency to see only what you want to see. You begin your software testing with the mindset of finding the bugs you already anticipate.

Cloud-Native Application Development Trends to Watch

The best measure is what will work best for the software to be tested. Knowing the nature of both test methodologies, which one will work the best. On average, exploratory testing discovers 11% more overall defects than scripted testing.

  • In exploratory testing, test cases are not documented and each test case is usually recorded in a testing spreadsheet.
  • This also allows you to easily compare the results of different testing phases or team members.
  • Tosca also enables testers to rapidly define sessions, charters, and test objectives, and Tosca provides a central location for recording testers, timeboxes, and related information.
  • Tricentis offers a Continuous Testing platform that is reinventing how software testing is integrated into DevOps.
  • Exploratory Testing – is usually performed in the moment and the tests cannot be reviewed in advance.

In fact, this can then be delegated to other testers who may not be experienced enough or who do not have the domain knowledge. This frees up the more senior testers to take up exploratory testing to ensure that all those edge cases and user journeys are checked. Scripted testing is straightforward and easy to follow as it depends on documentation and user requirements. Testers follow this type of testing approach as it helps them follow the right sequence of test cases and record the results for a better analysis. Scripted testing differs from the exploratory testing that QAs use when they have deep technical and domain knowledge about AUT. For comprehensive testing of an application, the combination of exploratory testing and scripted testing should be used.

By team size

This implicates that the longer the time a tester devotes for testing; the lower will be the productivity of the tester. The test charters are used to outline the areas and features or functionality of the application which are important. The testers are free to use their own testing approach within those parameters.

In this scripted testing skilled resources, well scripted instructions and test cases and verification are required. Exploratory testing is often used when there are many unknowns about what exactly the software is meant to do or how it should be used in real-world situations. In these cases, the goal is to explore the software rather than to follow a rigid plan or test a specific set of features. The tester may choose to perform Exploratory testing with no plan at all or may adjust their approach based on what they are learning while exploring. Exploratory tests tend to find more bugs than scripted, automated tests.

Scripted testing advantages

Scripted Testing – is usually very time intensive up front in order to write each step within a test case. Also, if the steps are too specific, they can become invalid or irrelevant if the deliverables are amended or changed. This would require maintenance to go back through and ensure that the test cases are still valid. Is cognitively https://globalcloudteam.com/glossary/scripted-testing/ structured as compared to the procedural structure of scripted testing. A test lead usually guides the testing team, the lead prepares the test cases and the testers perform the execution. This technique involves pre-planning of each subsequent steps to be followed in the execution of test plan for a specific component.
