From the documentation you need to add modulePathIgnorePatterns which is an array of string values which will be matched against
modulePathIgnorePatterns [array<string>] #
(default: []) An array of regexp pattern strings that are matched
against all module paths before those paths are to be considered
‘visible’ to the module loader. If a given module’s path matches any
of the patterns, it will not be require()-able in the test
environment. These pattern strings match against the full path. Use
the <rootDir> string token to include the path to your project’s root
directory to prevent it from accidentally ignoring all of your files
in different environments that may have different root directories.
Example: [‘<rootDir>/build/’].

Add this to your configuration…
modulePathIgnorePatterns: ["directoryNameToIgnore"]
or:
modulePathIgnorePatterns: ["<rootDir>/dist/"]
