Declaration
Represents a code declaration extracted from Dart source files during
static analysis.
FormatValidator
Validates that the generated test file follows Dart formatting conventions.
GeminiChat
A wrapper around the Gemini ChatSession.
GeminiModel
A wrapper around the Gemini GenerativeModel for creating, configuring,
and interacting with Gemini model.
GenerationResponse
Result object returned after attempting to generate tests.
PromptGenerator
A utility for generating different LLM prompt templates for code
generation and analysis.
TestExecutionValidator
Validates that the generated tests executed successfully without failures.
TestGenerator
Class coordinates the LLM interaction, validation, and file writing
required to generate a valid test for a Dart source code.
ValidationResult
Validator
Interface for all validation checks that can be run on test files.
Properties

Functions
buildDependencyContext (Declaration declaration , {int maxDepth = 10 → Map <Declaration ?List <Declaration
Builds a context map for a given declaration, by traversing its
dependencies up to maxDepth levels deep.
Extracts Declaration s from the given package.
Extracts declarations that have untested code lines based on coverage data.
formatContext (Map <Declaration ?List <Declaration parentMap → String
Formats the context map produced by buildDependencyContext into a
human-readable string, including code snippets and their file paths.
formatCoverage (Map <String dynamic > coverageResults , String packageDir → Future <CoverageData
Formats raw coverage results into a CoverageData structure.
formatUntestedCode (Declaration declaration , List <int lines → String
Returns the code for declaration after marking the specified lines
as untested, and wrapping it in the parent declaration's context if exists.
runTestsAndCollectCoverage (String packageDir , {String vmServicePort = '0' , bool branchCoverage = false , bool functionCoverage = false , bool isInternalCall = false , required Set <String scopeOutput → Future <Map <String dynamic >
Runs Dart tests in the specified packageDir and collects coverage data.
validateTestCoverageImprovement ({required Declaration declaration , required int baselineUncoveredLines , required String packageDir , required Set <String scopeOutput , String vmServicePort = '0' , bool branchCoverage = false , bool functionCoverage = false → Future <bool
Called after generating a test for the given declaration to check whether
coverage improved by comparing current uncovered lines with those
before the test was generated.
