Memory

Memory is the module that allows to easily store and share data between steps. To start using memory just import corresponing class into your tests.

To get element from storage call parseValue() method with argument. If you pass simple string that parseValue will return it as is.

const Memory = require("@cucumber-e2e/memory").Memory;
Memory.setValue("YourKey", "Your Value");
Memory.parseValue("$YourKey"); //"Your Value"

You can also parse string and replace {memoryKey} patterns with memory values via parseString() method.

const Memory = require("@cucumber-e2e/memory").Memory;
Memory.setValue("YourKey", "Your Value");
Memory.parseString("String with {$YourKey}"); //"String with Your Value"

Moreover memory module implements several classes to define and store static constant and dynamical values

Define computed value

const Memory = require("@cucumber-e2e/memory").Memory;
const AbstractComputedMap = require("@cucumber-e2e/memory").AbstractComputedMap;

class ComputedMap extends AbstractComputedMap {
    constructor() {
        super();
        this.defineComputed(/^FUNCTION$/, () => {
            return "value"
        });
    }
}
Memory.setComputedInstance(new ComputedMap()); //attach ComputedMap to Memory
Memory.parseValue("#FUNCTION"); //"value"

Define constant

const Memory = require("@cucumber-e2e/memory").Memory;
const AbstractConstantMap = require("@cucumber-e2e/memory").AbstractConstantMap;

class ConstantMap extends AbstractConstantMap {
    constructor() {
        super();
        this.defineConstant("constantKey", "value");
        this.defineFileConstant("fileConstantKey", "./test/file.txt");
    }
}
Memory.setConstantsInstance(new ConstantMap()); attach ConstantMap to Memory
Memory.parseValue("!constantKey"); //"value"
Memory.parseValue("!!fileConstantKey"); // data from "./test/file.txt" file
