¿Podemos tener dos llamadas simuladas Http en un solo método de clase de prueba?

Aug 17 2020

En Mi método haciendo dos llamadas en una sola transacción

Obtener token de acceso para esa API --> GetAccessToken
Ejecutar pago

Cuando ejecuté la clase de prueba, obtuve el siguiente error 08:50:00:839 FATAL_ERROR System.NullPointerException: Argument 2 cannot be null. en este codigo request.setHeader('Authorization', accessTokenValue);

En mi respuesta de maqueta, configuro Solo en Ejecutar pago. ¿Podemos simular la API de token de acceso con el mismo método? Dado que la respuesta de clase simulada es única execute Payment, no se puede realizar la llamada del token de acceso, por lo que accessTokenValuese establece como NULL.

¿Hay alguna manera de que podamos tener múltiples simulacros en un solo método de clase de prueba? Guíame en esto. Gracias

Sí, puedes, usando cualquiera de las dos técnicas.

Su método puede inspeccionar su entrada HttpCalloutMocky construir una respuesta diferente en función del punto final al que se llama, los parámetros pasados, etc. Esto le permite escribir una sola clase que devuelve respuestas para múltiples llamadas realizadas en secuencia en su código bajo prueba .respond()HttpRequest

Alternativamente, puede optar por utilizar la MultiStaticResourceCalloutMockclase. Esta clase le permite almacenar cuerpos de respuesta en recursos estáticos dentro de su aplicación y configurar el simulacro para múltiples puntos finales llamando setStaticResource()una vez por punto final al que desea que responda el simulacro. Esto puede ahorrarle la escritura de código repetitivo, si no le importa almacenar sus respuestas en recursos estáticos en lugar de construirlas en código.
