Code coverage thresholds for code segments based on usage frequency and change frequency

A method comprising:

• determining a usage frequency of a particular code segment of application code;
• determining a change frequency of the particular code segment;
• selecting the particular code segment for a code coverage threshold update based on at least one of the determined usage frequency and the determined change frequency;
• and
• updating the code coverage threshold of the particular code segment based on a previous code coverage level of the particular code segment, the determined usage frequency, and the determined change frequency.

A non-transitory machine-readable medium comprising instructions executable by a processing resource to:

• identify a first set of code segments of application code, wherein:
• each code segment within the first set has a usage frequency that satisfies a usage frequency criterion;
• and
• the usage frequency of a code segment specifies a number of other code segments in the application code that use the code segment;
• identify a second set of code segments of the application code, wherein:
• each code segment within the second set has a change frequency that satisfies a change frequency criterion;
• and
• the change frequency of a code segment specifies a number of commit actions applied to the code segment through a source control program over a predetermined time period;
• and
• for each particular code segment in at least one of the first set and the second set:
• apply a code coverage adjustment function to the particular code segment that determines a code coverage threshold for the particular code segment based on a previous code coverage level of the particular code segment, the usage frequency of the particular code segment, and the change frequency of the particular code segment.
