Black box testing vs white box testing

Combine black box, gray box and white box testing for the most comprehensive analysis of your application.Black box tests are developed from sources such as user stories and functional specifications. They enable QA to focus on verifying features and usability without reliance on the underlying code. This can help catch defects that might be missed due to assumptions about the code.

By contrast, white box tests such as unit and integration tests are created with an understanding of the internals of the application and access to the source code. White box testing may catch defects that are unobserved or that can’t be tested directly in the user interface. Gray box tests combine the other approaches: they are developed from the user perspective, but with some understanding of how particular features were implemented.

A combination of black box, grey box and white box testing allows you to benefit from the strengths of each approach and offset the drawbacks.

Blackbox testing approaches

What are black box testing techniques?

In black box testing, functional test cases are developed through analysis of the available documentation, including requirements, specifications, user stories or scenarios. The black box approach can also be used for non-functional tests, such as security and performance tests. Some common black box testing approaches are described below:

Icon edge case testing

Edge cases

Edge cases validate the minimum and maximum acceptable value of a single field, such as for a date or the length of a password.  So if a field should allow entries in the range from 1 to 100, create one test case for the value of 1, and another for the value of 100. It is not necessary to test all of the values in between.

Icon corner case testing

Corner cases

Corner cases test combinations of edge cases. The idea here is that while the individual fields may work properly, the combination may not. For example, if your application accepts a start date and an end date, a corner case would check a combination such as the earliest possible start date with the earliest possible end date.

Icon boundary value analysis

Boundary cases

Boundary cases test values just outside and inside of the edge cases. To test value that is valid between 1 and 100, create edge cases for 0, 1 and 2; plus 99, 100 and 101.  If the application handles the boundary values properly, then all other values should be handled correctly as well. This technique is also referred to as “boundary value analysis.”

Icon user scenario testing

User scenario cases

Scenarios describe the goal that a user wants to accomplish, such as checking their account balance or changing their password. In behavior-driven development (BDD), scenarios follow a specific “Given-When-Then” syntax that facilitates the creation of test cases.

Icon decision table testing

Decision table testing

In this formal testing technique, the causes/inputs and effects/outputs in the application are arranged in a table, with each cell containing a unique cause/effect combination. Then a test case is created for each cell value.

Icon error guessing technique

Error guessing

In error guessing, testers use their knowledge of the system and experience to guess the types of defects that may exist, and build test cases for them. This technique is similar to exploratory testing, as both rely heavily on the skill and knowledge of the tester.

Get the automated black box testing tools you need

With Ranorex Studio, everyone on the team can build automated tests without access to the underlying code with powerful tools for object recognition, capture-and-replay, a shareable object repository, customizable reporting, and more.

Icon tester-friendly automation

User-friendly test automation tools

If you are automating a test without access to the application’s source code, a capture-and-replay tool is essential. Testers with little or no experience in programming can build reliable tests without writing a single line of code. Easily add complex validations,  set parameters, define conditions for execution, create loops, and handle errors.

Icon Ranorex spy tool

Powerful object recognition

Instantly track and analyze UI elements of your desktop, web, or mobile application.  View detailed control information for each UI element, as well as its unique RanoreXPath – a powerful object identification syntax that minimizes maintenance when the UI changes. Manage identified objects in a shareable repository to further reduce maintenance.

Icon data-driven testing

Data-driven testing

Easily automate your corner, edge and boundary cases. Just set up variables in your test cases, and link them to external data sets such as simple data tables, SQL connectors, or Excel files. Your test case will loop through the data. You can decide whether a failure should stop the entire test run, continue with the next test case, or continue with the next loop. 

Icon keyword-driven testing

Keyword-driven testing

Create test modules for steps such as launch application, login, and save, and then store these in the user code library for easy re-use.  With Ranorex Studio’s support for keyword-driven testing, you can combine code modules and repository objects into sophisticated tests. Easily add execution loops, use conditional logic, and set values with local or global parameters.

Icon cross-device testing

Cross-device and cross-browser testing

 With Ranorex Studio, you can automate tests on a Windows desktop, and then execute them locally or remotely, on real iOS or Android mobile devices or on simulators/emulators. Run tests in parallel or distribute them on a Selenium grid to accelerate cross-browser testing for Chrome, Firefox, Safari, Microsoft Edge, and more.

Icon reporting

Customizable reporting

Monitor the results of testing with a customizable report that includes pie charts, screenshots, and detailed error logs. Save the report as a PDF or automatically receive it as an email attachment. Generate JUnit-compatible reports for easy integration with CI tools. Jump into to a failed test step directly from the test report, or use the maintenance mode to repair test cases during the test run.

Build a complete black box testing toolchain

Integrate Ranorex Studio with your BDD process, source control CI server, defect tracking solution, and more. Maximize your testing resources and improve collaboration with a complete toolchain for black box testing. Start by integrating your BDD process with Ranorex Studio’s support for SpecFlow. Integrate with a test management solution such as TestRail to coordinate manual and automated testing and view a comprehensive test report.  Manage your automated test cases in a source code repository such as Git, Subversion or Team Foundation Server. Trigger tests from a Continuous Integration server such as Jenkins or Bamboo, and report results to a defect-tracking solution such as JIRA or Bugzilla.
