Automating tests is generally more expensive than manual testing in terms of initial setup and development costs. However, once automated tests are created, they can be run repeatedly with minimal additional cost. In contrast, manual testing typically requires human testers to perform the same tasks repeatedly, which can be more time-consuming and expensive in the long run.

It ' s worth noting that creating automated scripts for every manual test is not always the cheapest and best way to automate. Automating tests that are not frequently run or that do not provide much value in terms of detecting bugs or improving product quality may not be the best use of resources. Automated tests should be selected based on the goals of the testing and the expected return on investment.

Manual testers can run tests that an automated test would lack the context to interpret, and automated test script may not excel in interpreting the context of the testing. It depends on the scenario and the automation approach.

The Document Object Model (DOM) is an API interface which treats an HTML document as a tree-like structure, where each node represents an object. It allows for manipulation of the HTML document, allowing for the creation, modification, and deletion of elements and their attributes. It is useful for creating dynamic webpages and applications.

The best line of code for changing the context of the test script to the frame with an ID of " framelD " is: fr = driver.find element by id( ' framelD ' ) driver.switch to.frame(fr)

Short-term thinking and inadequate planning for the automation is a limitation of a test automation project that is likely to cause an organization to get less return on their investment than they expected. Automation should be planned out carefully, with realistic expectations and goals in mind. It is also important to consider potential risks, such as the cost of long-term maintenance and the potential for automation to cause more problems than it solves. Additionally, it is important to consider the time and resources needed to create and maintain the automation, as well as the potential benefits and ROI of investing in automation.

The correct methods for finding an element by its class name are A. find element by css selector and D. find element by tag name. The find element by css selector() method can be used to locate an element by its class name, while the find element by tag name() method can be used to locate an element using the tag name of the element (such as ' div ' , ' span ' , ' a ' , etc).

An encompassing frame on an HTML page which can be used to embed another HTML document inside the first one. An iframe (Inline Frame) is an HTML element which allows you to embed another HTML document inside the current HTML document. It is typically used to embed external content such as videos, images, or documents into an HTML page. An iframe is an encompassing frame on an HTML page which can be used to embed another HTML document inside the first one.

The resulting web page would be: Section Name paragraph text • first • second • third

A closing tag is used to indicate the end of an HTML element. It is typically in the form of " < /element > " . For example, the closing tag for the < html > element is < /html > . This tag is used to indicate the end of the HTML document.

Selenium IDE (Integrated Development Environment) is primarily used for capture/playback. Selenium IDE is a Firefox plugin that allows testers to record and playback user interactions with a web application. It can be used to quickly create automated tests that can be used to verify the functionality of the System Under Test (SUT). It is also easy to set up and use [1] , making it ideal for those with limited technical understanding.
