In order to train the GPT-2 model we need some data, and to investigate how bias can affect the output of text generation we will experiment with political manifestos to see how text generation can be skewed to the political left and right. Getting the raw data The manifestos for…
After the concept of AI was first defined in the mid 1950’s, development was largely theoretical and severely restricted by the capabilities of compute resources available. Other than outwardly convincing but internally simplistic ‘chattterbox’ implementations, little progress was made initially. Rudimentary AI systems in the form of expert systems appeared…
In the post on UI testing with Selenium – record and refactor, the tests ran locally using Chrome. They were subsequently modified to run faster by running Selenium tests in parallel. For tests to be actually useful in the real world, they need to run on multiple browsers, on different…
In the posting on Selenium Testing, the tests run one after the other. For very small tests this is usually fine, but as the test pack increases in size, it will be advantageous to decrease the test execution time by running the tests in parallel. JUnit 5 options The JUnit…
Capturing screenshots of the browser via Selenium is fairly easy to achieve (see a sample method here), but triggering a screenshot only when a test fails is useful for both debugging and result reporting, however this requires a little more code and some modifications to your tests. JUnit5 For Junit5,…
Developing tests for web based front end applications can be a time consuming task – once you have identified the test cases you wish to automate, you have to examine the UI components of the application and determine the best locators to use for each element.Once the initial prototype tests…
In an earlier post we looked at Kafka and got hands on with creating topics, and producing and consuming messages. However, the basic tools are limited and only simple manual testing would be possible. Ideally we want to write automated tests, as these are repeatable and allow us to use…
Message brokers such as Kafka are very popular back end technology that testers may encounter, especially in a microservices based product architecture. Message brokers and message queues differ from API based request and response services in that the component subscribes to messages that could arrive at any time rather then…
