Explore the diverse categories of tests within our LangTest library, providing valuable insights into the varied testing procedures.
Accuracy Tests
Accuracy testing is crucial for assessing the performance of a model. It evaluates the model’s predictive capability on unseen test data by comparing predicted outcomes with actual results. This involves various tests, including labelwise metrics such as precision, recall, and F1 score, along with overall metrics like micro F1, macro F1, and weighted F1. These metrics provide a detailed analysis of the model’s accuracy and effectiveness.

Bias Tests
Model bias tests aim to gauge how well a model aligns its predictions with actual outcomes. Detecting and mitigating model bias is essential to prevent negative consequences such as perpetuating stereotypes or discrimination. This testing explores the impact of replacing documents with different genders, ethnicities, religions, or countries on the model’s predictions compared to the original training set, helping identify and rectify potential biases.
Examples
| Original | Test Case |
|---|---|
| Ms. Hope will be here soon. | Ms. Mcgary will be here soon. |
| Indonesia is one of the most populated countries. | U.S. is one of the most populated countries. |

Fairness Tests
Fairness testing is essential to evaluate a model’s performance without bias, particularly concerning specific groups. The goal is to ensure unbiased results across all groups, avoiding favoritism or discrimination. Various tests, including those focused on attributes like gender, contribute to this evaluation, promoting fairness and equality in model outcomes.

Robustness Tests
Model robustness tests evaluate a model’s ability to maintain consistent performance when subjected to perturbations in the data it predicts. For tasks like Named Entity Recognition (NER), these tests assess how variations in input data, such as documents with typos or fully uppercased sentences, impact the model’s prediction performance. This provides insights into the model’s stability and reliability.
Examples
| Original | Test Case |
|---|---|
| Amazing food! Great service! | Amzn food! Gr8 service! |
| Make sure you’ve gone online to download one of the vouchers - it’s definitely not worth paying full price for! | Make sure u’ve gone onl 2 d/l one of da vouchers - it’s dfntly not worth paying full price 4! |

| This program was on for a brief period when I was a kid, I remember watching it whilst eating fish and chips. Riding on the back of the Tron hype, this series was much in the style of streethawk, manimal, and the like, except more computery. There was a geeky kid who’s computer somehow created this guy - automan. He’d go around solving crimes and the lot. All I really remember was his fancy car and the little flashy cursor thing that used to draw the car and help him out generally. When I mention it to anyone they can remember very little too. Was it real or maybe a dream? | I remember watching a show from my youth that had a Tron theme, with a nerdy kid driving around with a little flashy cursor and solving everyday problems. Was it a genuine story or a mere dream come true? |
