A method , comprising: relating , by at least one computer processor, a user interface, UI, output with a corresponding localization object in a code-base index by creating, appending, or modifying at least one entry in the code-base index , providing information to the code-base index identifying a given UI output and link the given UI output identified to at least one specific location in a code base of the code-base index ; matching , by the at least one computer processor, a first instance of a unique identifier with a second instance of the unique identifier, wherein the first instance of the unique identifier is located in the code base corresponding to the code-base index , wherein the second instance of the unique identifier corresponds to the UI output , and wherein the code base is structured to comprise the unique identifier in a given context; retrieving , by the at least one computer processor, a reference to the corresponding localization object related to the UI output in response to a localization testing, wherein the localization testing is automated and flags errors, by applying rules configured to identify a frequent pattern of faulty agreement by context-insensitive concatenation of strings or contextually mismatched text found in localized UI output for a given localization target language, the automated localization testing determining that the UI output is incorrect in the given context; and outputting , by the at least one computer processor, the reference to the corresponding localization object in the code-base index into a ticket of an issue tracking system responsive to the determination that the UI output is incorrect, wherein the corresponding localization object is accessible from the ticket using the reference to the corresponding localization object . relating , by at least one computer processor, a user interface, UI, output with a corresponding localization object in a code-base index by creating, appending, or modifying at least one entry in the code-base index , providing information to the code-base index identifying a given UI output and link the given UI output identified to at least one specific location in a code base of the code-base index ; matching , by the at least one computer processor, a first instance of a unique identifier with a second instance of the unique identifier, wherein the first instance of the unique identifier is located in the code base corresponding to the code-base index , wherein the second instance of the unique identifier corresponds to the UI output , and wherein the code base is structured to comprise the unique identifier in a given context; retrieving , by the at least one computer processor, a reference to the corresponding localization object related to the UI output in response to a localization testing, wherein the localization testing is automated and flags errors, by applying rules configured to identify a frequent pattern of faulty agreement by context-insensitive concatenation of strings or contextually mismatched text found in localized UI output for a given localization target language, the automated localization testing determining that the UI output is incorrect in the given context; and outputting , by the at least one computer processor, the reference to the corresponding localization object in the code-base index into a ticket of an issue tracking system responsive to the determination that the UI output is incorrect, wherein the corresponding localization object is accessible from the ticket using the reference to the corresponding localization object . <EOS>
