It happens at almost every early-stage startup: a major bug escapes into prod (or into an investor demo). For teams without meaningful quality controls in place, the common reactions are dismay, embarrassment, and the instinct to "hire someone who can own quality." In these cases, “quality” generally means a lack of bugs. While the logic seems sound – there’s a quality issue, so we should hire an expert to handle quality – this instinct is ultimately misguided.

As we explained in a previous post, where we explained What End-2-End Testing is, we described End-to-end tests as a frequent type of automated testing used to ensure that your websites work properly (sometimes called e2e tests). Remember we pointed out that these tests mimic the steps that a typical user would do while accessing your application using a web browser.

It will not be an overstatement to say that some of the most revolutionary breakthroughs have been driven by and taken place in the aviation industry. Decades ago, jet engines catapulted the airline industry out of capacity constraints, enabling it to carry many more travelers. The deregulation of the airline industry provided flexibility and freedom for players to set competitive ticket prices.

Developers prioritize implementing changes rapidly in an agile environment. When updating a front-end component, they must perform cross-browser testing. Web apps’ technological and functional capabilities have continuously increased over the years. Automated testing is necessary to ensure that these functionalities and the UI are functioning properly. Python is ranked third among programming languages in the Stack Overflow Developer Survey of 2021, after JavaScript and HTML/CSS.

Testing is the most critical part of the Software Development Life Cycle(SDLC). Testing is performed at different levels such as Unit Testing, Integration Testing, and Functional Testing. Testing can be performed either manually or through automation. The tools or libraries which are used for test automation vary with the framework that you are using. For example, if you are using a JavaScript framework, you might have to use Jasmine, Jest, etc.

Browser emulators are ideal for testing how responsive a site is. The term ‘browser emulator’ refers to software that imitates the functionality of various web browsers. For instance, a Safari emulator aims to emulate Safari. Emulators help attain the exact look and feel of an actual Safari browser when a website is launched on it. Safari is a popular browser exclusive to Apple devices.
