存储对象供以后在java中使用

Question

I'm working on API testing automation using Rest assured. I would like to store Response as an object after calling an API so I can validate some data using that object like, status code, body, header and all.

I tried using System.setPropery but it allows to store only String and if store Response as String like System.setProperty("test", response.toString()); and try to retrieve System.getProperty("test"); then throws the error

java.lang.ClassCastException: java.lang.String cannot be cast to io.restassured.response.Response

It there a way to store an object somewhere and access it for later use?

Answer 1

Don't use System.Properties for this purpose. Please use a simple cache store as given below.

public class ResponseCache {
    private static final ResponseCache myInstance = new ResponseCache();

    private final Map<String, Response> cacheStore = new HashMap<>();

    private ResponseCache() {
    }

    public static ResponseCache getInstance() {
        return myInstance;
    }

    public void addResponse(String key, Response value) {
        cacheStore.put(key, value);
    }

    public boolean exists(String key) {
        return cacheStore.containsKey(key);
    }

    public void remove(String key) {
        if (exists(key)) {
            cacheStore.remove(key);
        }
    }

    public Response get(String key) {
        return exists(key) ? cacheStore.get(key) : null;
    }

}

Once your execution work is completed you can remove that key.
