Trial vs. Testing: What's the Difference?

Edited by Aimie Carlson || By Janet White || Updated on October 12, 2023
Trial refers to a test of performance, qualities, or suitability, while Testing involves systematic examination or assessment.

Key Differences

The term "Trial" often indicates an attempt to evaluate a certain aspect or capability. For example, a product trial is an opportunity for potential customers to try a product before purchasing. "Testing," on the other hand, involves a detailed examination or a methodological assessment to determine something's quality, safety, or functionality.
"Trial" can also refer to a formal examination of evidence by a judge, typically before a jury, in order to decide guilt in a criminal case or to make a judgment in a civil matter. "Testing" doesn't possess this judicial connotation; it's more related to verification processes in various contexts.
In many contexts, "Trial" conveys a sense of experimentation, like trying something out to see if it works or fits. Think of software trials or clinical trials. "Testing" suggests a more rigorous and structured evaluation, such as standardized testing in education or materials testing in engineering.
It's crucial to note that while both "Trial" and "Testing" can be about evaluation, their use might differ based on context. A "trial period" at a job refers to an initial period where one's fit and skills are assessed. Conversely, "testing" in the same context might involve specific exams or tasks set for the candidate to gauge competence.
Sometimes, the terms can be used interchangeably, especially in casual speech. You might hear someone say they're "trialing" a new software when they're technically testing it. However, discerning between "trial" as an opportunity to try and "testing" as a structured assessment can provide clearer communication.
