Obtain and Assert Numerical Values from Text Elements

Article Overview:

This article will cover how you can achieve the following:

• Extract numerical values from text elements for assertions.
• Convert and store extracted values into a numerical format for seamless use.

Problem Statement:

When extracting numerical values (e.g., "47,939 results") from text elements, the stored value often includes non-numerical characters, such as commas or additional text. This makes it difficult to perform direct assertions or numerical comparisons on the extracted values.

Solution 1:

Cleaning and Converting Text for Assertions:

To clean the extracted value and retain only the numbers:

• Apply the following JavaScript expression to strip out commas and convert the value to a number:

Store element details of "47,939 results" in $Result
Store value ${Number($Results.replace(/,/g,''))} in $Result
Assert that $Result is greater than 47000

This converts the text (e.g., "47939 results") into a numerical value (47939) stored in $Result.

Store value "Your code is: 123456" in $Result
Store value ${$Result.substring(22,13)} in $Result

• 22 is the starting index of the numerical portion in the string.
• 13 is the ending index.

Explanation:

• The substring(start, end) function extracts characters from the string based on the specified indices.
• This approach is useful when the numeric portion always occurs in a predictable location within the text.

Notes:

• Removing Commas:
  The replace(/,/g, '') removes all commas from the string, ensuring a clean numerical value.

• Converting to Numbers:
  The Number() function is essential to transform a cleaned string into a usable numerical format for calculations and assertions.

• Using Substring:
  Ensure you know the exact position of the numerical portion when using substring to avoid errors in extraction.
