A Tester’s Consistency Checklist

One of the many tests that I often do is a consistency test. It’s something that’s really hard to automate, and testing for it can unearth different sorts of problems, six of which I’ll detail in this post.

A Tester Checking a Software Application for Consistency

1. Consistency Between Screens

An app can evolve over time as new screens and forms are added. Do these new screens use the same terminology, layout, and colors as the existing ones?

2. Consistency Between App and Portal

It’s common for an app to also have a portal. Is the terminology consistent between them? Is the handling of data consistent–does the app allow values that the portal does not (and vice-versa)? Are there fields in the app that don’t appear in the portal (and vice-versa)?

3. Consistency Between App and Documentation

Are there are any user manuals, online help, or marketing materials? If so, do their descriptions and screen shots match the app? Often they are written only once and fail to get updated if any changes are made to the app.

4. Consistency with Standards, Laws, and Regulations

Does your app have to conform to any standards? Are there are any laws it has to follow? Are there any regulations that it has to meet?

5. Consistency with Older Versions

Can the latest version of the app handle file formats from previous versions? Has the terminology changed? Is the workflow different? Is button placement different? If there are differences, were these intentional?

6. Consistency with Environment

Is the app consistent with other apps or equipment in the same environment? If it is different, is this a problem or a feature?

A Worthy Process

As well as checking for any consistency errors, going through the app like this can also unearth other problems and give you ideas for more tests. It’s an exercise well worth doing.

Are there other types of problems you’ve discovered through consistency checks?
