In Codeship Basic is redis memory flushed after/before each build?

Question

I am using redis-based cache in my application. I am running my integration tests on Codeship Basic and measuring the code coverage. I often see that the code coverage is different for two subsequent builds that use redis cache.

My hypothesis is that redis memory is shared between builds. Is this true?

I am using the default redis at port 6379.

Answer 1

If Redis is utilizing the $HOME/cache directory within the build, then information would persist between builds. This seems unlikely as it would require a conscious configuration to make use of this directory.
