Search functionality is an interesting but complex area when it comes to testing. A search functionality is by definition a search engine, which deals with vast amounts of data and an underlying search algorithm built on complex statistical models. That’s not to mention the ever-increasing user expectations for the search feature to understand nuances in human language, capable of handling misspellings, synonyms, and natural language queries.

Understanding that challenge, in this article, we will list out the most common and essential test cases for search functionality and categorize them in groups. We also include asample test case document for this page so that you can get started more quickly.

Important Test Cases For Search Functionality

1. Test Cases For Search Functionality in Ecommerce Website

Ecommerce websites pose unique challenges when it comes to testing the search functionality due to the large volume of customers having high expectations for the search results. Many Ecommerce websites even employ predictive analytics to tailor the search results to the customer behavior. Here are some important test cases for the search functionality on Ecommerce websites:

1. Verify that the search bar is prominently displayed on the homepage.
2. Enter a valid product name and ensure relevant results are displayed.
3. Enter a query with multiple keywords and confirm accurate results.
4. Check if search results show product images, names, prices, and descriptions.
5. Verify that filters (e.g., sorting, category, price range) work correctly with search results.
6. Test the "Search As You Type" feature for real-time suggestions.
7. Ensure the search functionality supports auto-correction for misspelled words.
8. Test the pagination of search results when there are multiple pages of results.
9. Verify that the search results can be shared via social media or email.
10. Check if the search history is displayed and functional.
11. Test the responsiveness of the search feature on different devices (desktop, mobile, tablet).
12. Verify that the search functionality supports voice search.
13. Check if the "Did you mean?" feature provides relevant suggestions for ambiguous queries.
14. Test the speed of search results retrieval for a high-traffic scenario.
15. Verify that the search functionality integrates with the site's recommendation engine.

2. Negative Test Cases For Search Functionality

Users don’t always behave in the way we expect them to be. That’s why we also need negative test cases, which are test cases for invalid and unexpected conditions/scenarios. For example:

1. Enter an empty search query and ensure it provides an appropriate error message or doesn't initiate a search.
2. Search for a product or term that doesn't exist in the database and verify that it returns no results.
3. Use special characters (e.g., @, $, %) in the search query and validate how they are handled.
4. Enter a search query that exceeds the character limit allowed and verify how it's managed.
5. Attempt to search using data types other than text, such as numbers or symbols.
6. Search for a product or term using incorrect capitalization and verify if the search is case-sensitive or not.
7. Enter search queries that consist of common stop words (e.g., "and," "the") and ensure they are handled correctly.
8. Add unnecessary spaces at the beginning or end of the search query and confirm how it's treated.
9. Enter queries with unsupported characters or symbols that should be filtered or replaced.
10. Attempt to search while the website is undergoing maintenance or updates and assess how it's handled.
11. Conduct searches with a deliberately slow or unreliable network connection to test the system's response time.
12. Enter data in an incorrect format for the search query, such as entering a date in a text search.
13. Test if the sorting options (e.g., price low to high) work as expected and that they don't produce incorrect results.
14. Interrupt a search operation by navigating to a different page or clicking away and assess how it handles the interruption.
15. Attempt to search when the search feature is intentionally disabled or hidden and verify its behavior.
16. Enter mixed-language queries with text in different languages and check how it interprets and processes them.
    

3. Query Input Test For Search Feature

Before conducting this type of testing, note that there are several types of search methods used to retrieve information from databases, including:

• Keyword Search: the most basic type of search where users enter one or more keywords to find information matching those terms.
• Boolean Search: users can combine keywords using logical operators (AND, OR, NOT) to refine search results. This is usually considered as an Advanced search feature.
• Natural Language Search: Natural language search allows users to enter queries in plain, everyday language. This is a growing type of search withGoogle's upcoming SGE.
• Faceted Search: this method lets users filter search results based on predefined categories or attributes (facets). It's often used in e-commerce websites to refine product searches.
• Geospatial Search: this focuses on finding information based on geographic location or coordinates. It is commonly used in mapping and location-based services.
• Voice Search: while relatively new, voice search allows users to perform searches using voice commands or speech recognition technology.
  

Here are some common test cases for the query input:

1. Test single-word queries.
2. Test multi-word queries with spaces.
3. Enter queries with synonyms and ensure they yield consistent results.
4. Test queries with hyphens and special characters.
5. Use Boolean operators (AND, OR) in search queries and confirm correct behavior.
6. Verify the handling of upper and lower case characters in queries.
7. Test search queries withdiacritics andaccented characters
8. Enter queries with numeric values and check for relevant results.
9. Use wildcard characters (* or ?) in queries and validate their impact on results.
10. Test queries with stop words (common words like "and," "the") and verify they are handled correctly.
11. Enter queries with common misspellings and assess auto-correction.
12. Test voice search with both clear and accented pronunciation.
13. Verify the behavior when entering queries in different languages.
14. Test queries with geographic or location-based keywords.
15. Enter ambiguous queries and assess the accuracy of suggested alternatives.

4. Test Cases For Search Results Evaluation

The quality of search results is the main indicator of search functionality quality. The most important factor isrelevance: a good search result should closely match the user's query and provide information that is directly related to their search intent. Other aspects include:

• Completeness: does the search result include a comprehensive set of answers related to the original search input?
• Clarity:is the search result presented in an easy-to-understand manner?
• Consistency:can users predict where to find specific types of information within the results?
• Ranking by Relevance:are most relevant results ranked at the top and less relevant results ranked at lower positions?
• Rich snippets:are related product information (rating, product description, product title, etc.) included in the search results?

Here are some test cases to help you evaluate the search result quality:

1. Verify that the most relevant results appear at the top of the list.
2. Test sorting options (e.g., price low to high) and validate correct order.
3. Check if the number of results matches the displayed count.
4. Test the display of product images for all search results.
5. Verify that product names and descriptions match the query.
6. Test the accuracy of displayed product prices.
7. Check if product ratings and reviews are correctly associated with search results.
8. Enter a query for a specific brand and verify that only relevant products are displayed.
9. Test the "Quick View" feature to ensure it opens the correct product details.
10. Verify that product availability (in stock/out of stock) matches the search results.
11. Test the display of related products or suggestions alongside search results.
12. Check if sponsored or promoted products are clearly labeled.
13. Test the behavior when a user clicks on a search result link.
14. Verify that search results can be easily added to a shopping cart or wish list.
15. Test the performance of search results loading under heavy user traffic.
