1. A method comprising: receiving a command to convert an application associated with a first programming language into a first version and a second version; accessing source code of the application by a first converter to generate a first translation of the source code in a second programming language, wherein, responsive to detecting a first flag in the source code indicating a design pattern, the first converter conforms at least a portion of the first translation to the design pattern; accessing the source code by a second converter to generate a second translation of the source code in a third programming language that differs from the second programming language, wherein, responsive to detecting the first flag in the source code, the second converter conforms at least a portion of the second translation to the design pattern; after identifying a second flag in the source code and identifying a unit test portion of the source code based on the second flag, the unit test portion including first unit tests in the first programming language, generating second unit tests in the second programming language that are associated with the first translation and that correspond to the first unit tests, third unit tests in the third programming language that are associated with the second translation and that correspond to the first unit tests, or a combination thereof, wherein the second unit tests are generated by the first converter, and wherein the third unit tests are generated by the second converter; and outputting the first translation and the second translation to a first device and a second device, respectively.
