Hope you have got a basic understanding of these tools. This Chai Mocha framework is frequently used for unit testing by developers to perform tests and report results. By using Chai with Mocha the user can get the results in the required format. While Chai is an assertion library that is used to validate the test case results. The results of these tests are displayed on the terminal window. Mocha is a simple testing framework that will allow you to execute a set of functions in sequence. With Puppeteer you can take a deep dive into Chrome functionalities easily which could be a challenge when it comes to other open-source automation tools.Ĭhai and Mocha are JavaScript frameworks that are commonly used together. In simpler terms, being from the same parent gives it greater control and flexibility to work with Chrome. Now Puppeteer is a node.js library from Google as well, which gives you a high-level API control over Chrome and Chromium using the DevTools protocol. When it comes to web automation the most commonly used browser is Chrome which is from Google. There are several other advantages as well when it comes to Selenium. Multiple browser support means that we can use it for cross-browser testing as well. This tool has become so popular because of the flexibility and controls it offers in execution the commands on the browser. This is also an open-source tool that makes it more acceptable to companies. This enables even developers to write create and execute automation test cases through Selenium. It also supports scripting in several languages including Java, Python, and C#. Selenium has established itself as the most popular web browser automation tool with support for most of the available browsers including Chrome, Mozilla, Opera, and Safari, etc. There are several tools available for you to choose based on the kind of application you have like a web-based app or a mobile app or a desktop software etc. Now here is the challenge, many small and even big companies are going to the open-source automation tools which give them the flexibility to customize as per their need without any investment. Most teams take the help of automation tools. Since testing is still a task on our User Stories, it needs to be completed. This is what happens in real-life scenarios. To start with, the scope for manual testing has reduced. Who does that? How does it fit in the 2-week agile sprint? Is manual testing even possible in such a short time? Bottom line is testing still needs to be done. So much to an extent where the role of the tester has completely changed! With the coming in of the PDO ( Product Driven Organization) structure, there are no more testers and developers but only full-stack engineers. This is why our homes are wired up with parallel circuits.The software life cycle has undergone drastic changes in the last decade. Parallel circuits are useful if you want components to continue to work, even if one component has failed. And, unlike a series circuit, the lamps stay bright if you add more lamps in parallel. In a parallel circuit, if a lamp breaks or a component is disconnected from one parallel wire, the components on different branches keep working. A circuit with a battery and two lamps connected in parallel. If you follow the circuit diagram from one side of the cell to the other, you can only pass through all the different components if you follow all the branches. In parallel circuits different components are connected on different branches of the wire. They also use less wiring than parallel circuits. Series circuits are useful if you want a warning that one of the components in the circuit has failed. In a series circuit, if a lamp breaks or a component is disconnected, the circuit is broken and all the components stop working. If you put more lamps into a series circuit, the lamps will be dimmer than before. If you follow the circuit diagram from one side of the cell to the other, you should pass through all the different components, one after the other, without any branches.Ī circuit with a battery and two lamps connected in series You get several components one after the other. In a television series, you get several episodes, one after the other. If there are branches it's a parallel circuit. If there are no branches then it's a series circuit. The components in a circuit are joined by wires. There are two types of circuit we can make, called series and parallel.
