Linter Results Processor

Build a tool that processes structured linter output data and generates summary statistics. The tool should parse JSON input containing linter results and calculate key metrics about the findings.

Capabilities

Parse and normalize linter data

• Given JSON input with an array of file results, parse it successfully @test
• Given a result with filePath: "src/app.js" and messages: [{line: 10, column: 5, message: "Error", ruleId: "no-unused"}], extract all fields correctly @test
• Given a message with missing line field, default it to 0 @test
• Given a message with missing column field, default it to 0 @test
• Given a message with missing ruleId field, default it to empty string @test

Calculate statistics

• Given input with 3 messages across 2 files, return total count of 3 @test
• Given input with 2 files having messages and 1 file with empty messages array, count 3 total files @test
• Given input [{filePath: "a.js", messages: []}, {filePath: "b.js", messages: [{line: 1}]}], output "1 problem in 2 files" @test
