Cypress is a modern testing tool with built-in features, while Selenium is a widely-used open-source tool with a larger community.

• Cypress is known for its fast test execution and easy setup compared to Selenium.

• Selenium supports multiple programming languages, while Cypress uses JavaScript.

• Cypress has a built-in dashboard for easier test management, whereas Selenium requires additional tools for reporting.

• Cypress has a...read more

Use Selenium WebDriver to automate launching an ecomm website, searching for a product, performing pagination, and finding a particular product.

• Use Selenium WebDriver to automate browser actions

• Navigate to the ecomm website URL

• Locate the search bar and enter the particular product name

• Handle pagination by clicking on next page buttons or using page numbers

• Identify the particular product by its unique identifier or attr

Page object model is a design pattern used in test automation to create an object repository for web UI elements.

• Separates test scripts from web elements

• Improves code reusability and maintainability

• Enhances test readability and reduces duplication

• Each web page is represented as a class

Time series methods involve analyzing data points collected at regular intervals over time to identify patterns and trends.

• Time series analysis involves studying the past behavior of a variable to forecast its future values.

• Common methods include moving averages, exponential smoothing, and autoregressive integrated moving average (ARIMA) models.

• Time series data can be used in various fields such as finance, economics,

Bias-variance tradeoff is a key concept in tree-based algorithms, balancing model complexity and generalization ability.

• Bias-variance tradeoff refers to the tradeoff between bias (underfitting) and variance (overfitting) in machine learning models.

• Decision trees have high variance and low bias, while ensemble methods like Random Forest have lower variance and higher bias.

• Regularization techniques like pruning can help ...read more

Time series methods involve analyzing and forecasting data points collected at regular intervals over time.

• Time series analysis involves studying patterns, trends, and seasonality in data over time.

• Common methods include moving averages, exponential smoothing, and ARIMA models.

• Forecasting techniques such as Holt-Winters method and machine learning algorithms can be used for prediction.

• Time series data can be visualized...read more

Bias-variance tradeoff is a key concept in machine learning, especially in tree-based algorithms.

• Bias-variance tradeoff refers to the balance between underfitting (high bias) and overfitting (high variance) in a model.

• Decision trees tend to have high variance and low bias, while ensemble methods like Random Forest aim to reduce variance.

• Regularization techniques like pruning can help reduce overfitting in tree-based al...read more
