clock · Detalhes do pacote

Visão geral do pacote

Orientação gerada a partir de informações públicas. Apenas para referência.

O pacote clock fornece um wrapper falsificável em torno das APIs principais de relógio do Dart, permitindo o tratamento de tempo previsível e testável em aplicações. Ele abstrai operações de tempo do sistema como DateTime.now() e Duration, permitindo que os desenvolvedores simulem diferentes momentos no tempo durante os testes. Isso é especialmente útil para testes unitários e de integração que envolvem temporizadores, tarefas agendadas ou lógica baseada em tempo. O pacote suporta todas as principais plataformas e se integra perfeitamente com projetos Flutter.

Casos de uso

Teste de lógica dependente do tempo
Simulando datas futuras ou passadas
Mocando o tempo do sistema em testes unitários
Construindo cronômetros de contagem regressiva
Implementando ações diferidas

Principais recursos

Tempo do sistema falso
Comportamento consistente em testes
Sobreposição mínima
Suporte multiplataforma
Integração fácil com código existente

Indicado para

Desenvolvimento guiado por testes
Recursos de aplicativo sensíveis ao tempo
Frameworks de teste automatizado
Aplicativos Flutter com cronômetros
Desenvolvedores que precisam de comportamento de tempo determinístico

Considerações

Não destinado ao tratamento em tempo de produção
Requer uso explícito do invólucro
Pode ser necessário refatorar o código dependente de tempo
Limitado a operações básicas de tempo
Melhor usado apenas em ambientes de teste

Overview

This repository is home to tooling related Dart packages. Generally, this means packages published through the tools.dart.dev publisher that don't naturally belong to other topic monorepos (like dart-lang/build, dart-lang/test, or dart-lang/shelf).
