When executing Jest, why do Typescript paths fail to resolve?

edit

There could be several reasons why Typescript paths fail to resolve when executing Jest.

One common reason is that Jest may not be aware of the Typescript configuration file. In this case, setting up Jest to use the ts-jest transformer and adding the appropriate configuration options in the Jest config file should resolve the issue.

Another reason could be that the module resolution strategy in Jest is different from the one specified in the Typescript configuration file. Jest may be looking for modules in the node_modules directory rather than using the specified Typescript paths. In this case, updating the Jest config file to use the same module resolution strategy as the Typescript config file can resolve the issue.

Additionally, it is important to ensure that the path aliases defined in the Typescript configuration file are correctly specified and match the actual paths of the modules. Incorrect or mismatched paths can cause Jest to fail to resolve the modules correctly.

Finally, it is possible that there may be errors in the Typescript configuration file itself that prevent Jest from correctly resolving the paths. Ensuring that the Typescript configuration file is error-free and correctly configured can help resolve this issue.
