There are several mature open source and proprietary tools for testing the user interface of mobile apps on Android and iOS devices, but there aren’t many solutions for internet service providers or video-on-demand streaming services who want to test video playback on real mobile devices to validate their end-to-end video delivery. In this article I’ll discuss various ways of getting video frames from a mobile device for automated testing, and the advantages and trade-offs of each approach. Read more...
Software update v27.3 for the stb-tester ONE is now available. It adds support for the Sony PlayStation 3 & 4, Android devices, and more! Read more...
To test a PS4 app you need a mechanism to control the PS4 and a way to get feedback to check that your app is behaving as it should. Read more...
The stb-tester camera allows you to test the user interface of devices that don’t have an HDMI output, such as Smart TVs and mobile devices. Read more...
A Serial Terminal Server makes a serial connection available over the network, so that your application can access your devices without a direct serial connection. Typically this is used to establish a bi-directional connection between networked applications and older industrial equipment. In this article we will focus on a much simpler use case: Capturing serial logs, where we only need communication in one direction — a common use case when testing set-top boxes. Read more...
Software update v26.6 for the stb-tester ONE is now available. It contains a JPEG thumbnail alternative to the Flash video in the web interface, and a bugfix for inode exhaustion on the stb-tester ONE’s test-results partition. Read more...
Selenium is a test automation tool for web applications. It tests your web app by looking at the DOM – you can check that your web page contains a particular element like a div or a button, identified by id or css selector or xpath expression; once the element is located, you can check that it contains a particular text or other elements. However you can’t really check what your web app looks like. If you have complex CSS it can be all too easy to introduce unintended defects in your app’s visual appearance. Read more...

If you have already automated one or more testcases, run them! Ideally run them every time a developer commits a change to the system-under-test. If that isn’t possible, at least run the tests against nightly builds. Run! Your! Tests! Read more...
We have just published an extensive tutorial about our recommended workflow for implementing automated test scripts, using stbt.FrameObject to extract information from the screen, using stbt lint and stbt auto-selftest to test your scripts locally, and using stbt-docker to develop on Mac or Windows.

In the previous blog post we discussed the frame object pattern and how it could lead to greater agility and lower maintenance costs thanks to improved self-testability. This blog post discusses a technique to get the maximum value from this testability at near-zero cost. Read more...
In the previous blog post we discussed the Page Object pattern and how it could be used to improve the readability of your test scripts. In this blog post we introduce the Frame Object pattern, a specialisation of the Page Object pattern that can be especially effective in stb-tester’s style of black-box UI testing1. Frame Objects can reduce the maintenance cost of your test-packs, particularly when the UI-under-test changes.
Often you will hear us recommend that you should structure your test-packs as a set of library functions, plus test-cases that use those library functions. In this blog post we attempt to make this recommendation more concrete by demonstrating how to apply the “page object” pattern when writing stb-tester test-cases. Read more...
In this blog post we use the OpenCV cv2.floodFill
function to improve the robustness of test helper functions for dynamic UIs.

Up until now, stb-tester testcases were Python scripts with one testcase per file, and you referred to your testcases by the filename. Read more...
We have overhauled the stb-tester Python API reference documentation, with more examples, introductory material, a categorised index, and a search function. Read more...
stbt batch run works really well for stress-testing and soak-testing, but
it’s lacking a few features that would be useful for functional acceptance
testing: Run each test once, then re-run each failing test; run the tests in a
random order or specify ordering dependencies between tests; update an external
bug database with the results. Or for a continuous integration service, only
run the fast tests and don’t fail the build if a test fails due to a known
defect. The list goes on.

Stb-tester’s wait_for_match function works well enough, but what if you want
to wait for a UI element to disappear? Or when you want to check that 2
different UI elements are present in the same frame? Or when you just want to
know if the element is present or not, without raising an exception? An
addition to stb-tester’s Python API, due in stb-tester 0.21, will make this
much easier.

Do you wish that your stb-tester test farm was as easy to set up as
Travis CI? Want a neat way of specifying your test script’s dependencies? Or
maybe you want to run stb-tester from your Windows PC? The upcoming stbt
service command solves these problems.

irrecord can be used to create them by recording IR
signals but can have difficulty sometimes. In those cases you can provide
additional information to make recording succeed which can be determined
from the output of mode2 and xmode2 and by consulting the lirc config
file documentation.stb-tester 0.20 has been released. The key new developments are: Read more...
A Continuous Integration (CI) system, which runs your automated tests against every change made to your source code, is an important part of every Agile development process. With stb-tester your CI system can run integration tests on the real target device. As a demonstration we have set up stb-tester CI for a simple “Hello World” Android app at this git repo.

stbt.ocr’s misreadings aren’t due to it not being familiar with your
fonts. The root cause is that the OCR system we use (tesseract) is
intended for reading the printed word. With this new understanding we’ve
made improvements to OCR resulting in a 12× reduction of errors. This will
be in the next stb-tester release.stb-tester 0.19.1 has been released. The only change since 0.19 is a fix to the Fedora packages to make them installable on Fedora 19. See the release notes for (not much) more information.
stb-tester 0.19 has been released. This is a beta release intended to allow for wider testing rather than production use. Read more...
stb-tester 0.18 has been released with support for OCR and enhancements to the test runner - now called stbt batch.
