Ideia Principal: Compreender os conceitos de touring, sidetrips e desvios em testes de software é fundamental para navegar e cobrir com eficácia caminhos complexos em um modelo baseado em gráficos, garantindo uma avaliação abrangente do comportamento do software sob condições variadas.
**Conteúdo
- Definições de Touring, Sidetrips e Detours:
- Touring: Diz-se que um caminho de teste percorre um subcaminho se ele seguir o subcaminho exatamente como definido. Touring é o processo de execução de um caminho de teste que cobre com precisão uma sequência especificada de nós e bordas.
- Sidetrips: Um caminho de teste que inclui sidetrips ainda percorre um caminho principal, mas pode se desviar temporariamente para cobrir nós ou bordas adicionais antes de retornar ao caminho principal. As viagens secundárias permitem que os testadores explorem funcionalidades e interações adicionais sem perder o foco no objetivo principal do teste.
- Desvios: Semelhantes aos desvios laterais, os desvios envolvem desvios do caminho principal, mas especificamente por meio de rotas alternativas que eventualmente retornam ao caminho principal em um ponto posterior. Os desvios são úteis para testar como as variações no fluxo afetam o estado ou os resultados do sistema.

Discussão sobre a viabilidade dos caminhos de teste:
- Caminhos viáveis vs. caminhos inviáveis: Nem todos os caminhos de teste projetados são viáveis devido a restrições do sistema ou inconsistências lógicas. O reconhecimento de caminhos inviáveis, como os que exigem condições contraditórias, é vital para refinar os planos de teste.
- Manuseio de requisitos de teste inviáveis: Nos casos em que determinados caminhos são identificados como inviáveis (por exemplo, devido a código morto ou cenários impossíveis), é importante documentar essas descobertas e ajustar as metas de cobertura de acordo. Isso pode envolver a revisão dos critérios de teste ou do próprio modelo gráfico.

Exemplos e implicações para os testes
- Exemplo de passeio com desvios e desvios:
graph LR;
Login[Login] --> Dashboard;
Dashboard --> Settings[Settings];
Dashboard --> Profile[Profile];
Settings --> Logout[Logout];
Profile --> Logout;
Login --> Logout;
style Login fill:#f4d03f,stroke:#333,stroke-width:2px
style Logout fill:#e74c3c,stroke:#333,stroke-width:2px
-
Neste exemplo, o caminho principal pode ser [Login, Dashboard, Logout]. Uma viagem secundária poderia envolver a visita a [Configurações] antes de [Logout], e um desvio poderia envolver a rota através de [Perfil], depois de volta a [Painel] e, finalmente, [Logout].

Tabela de estratégias de teste com turnês, viagens secundárias e desvios:
| Strategy | Description | Testing Implication |
|---|---|---|
| Touring | Following a path precisely as defined. | Ensures critical sequences are tested exactly. |
| Sidetrips | Deviating temporarily to cover additional functionality. | Explores extra features while maintaining core path. |
| Detours | Taking an alternate route but returning to a significant later point. | Tests response to variations in user flow. |
Atomic Note: Touring, Sidetrips, and Detours in Graph-Based Software Testing
Title: Navigating Complex Test Paths: Touring, Sidetrips, and Detours
Main Idea: Understanding the concepts of touring, sidetrips, and detours in software testing is crucial for effectively navigating and covering complex paths in a graph-based model, ensuring a comprehensive evaluation of the software’s behavior under varied conditions.
Content:
- Definitions of Touring, Sidetrips, and Detours:
- Touring: A test path is said to tour a subpath if it follows the subpath exactly as defined. Touring is the process of executing a test path that precisely covers a specified sequence of nodes and edges.
- Sidetrips: A test path that includes sidetrips still tours a primary path but may temporarily deviate to cover additional nodes or edges before returning to the main path. Sidetrips allow testers to explore additional functionalities and interactions without losing focus on the primary test objective.
- Detours: Similar to sidetrips, detours involve deviations from the primary path, but specifically through alternate routes that eventually rejoin the main path at a later point. Detours are useful for testing how variations in the flow affect the system’s state or outputs.

Discussion on the Feasibility of Test Paths:
- Feasible vs. Infeasible Paths: Not all designed test paths are feasible due to system constraints or logical inconsistencies. Recognizing infeasible paths, such as those requiring contradictory conditions, is vital for refining test plans.
- Handling Infeasible Test Requirements: In cases where certain paths are identified as infeasible (e.g., due to dead code or impossible scenarios), it’s important to document these findings and adjust the coverage goals accordingly. This may involve revising the test criteria or the graph model itself.
-
Examples and Implications for Testing:
- Example of Touring with Sidetrips and Detours:
graph LR;
Login[Login] --> Dashboard;
Dashboard --> Settings[Settings];
Dashboard --> Profile[Profile];
Settings --> Logout[Logout];
Profile --> Logout;
Login --> Logout;
style Login fill:#f4d03f,stroke:#333,stroke-width:2px
style Logout fill:#e74c3c,stroke:#333,stroke-width:2px
-
In this example, the primary path might be [Login, Dashboard, Logout]. A sidetrip could involve visiting [Settings] before [Logout], and a detour could involve routing through [Profile] then back to [Dashboard] and finally [Logout].
