java - 如何使用 TestRunner 和 cucumber 注入(inject) TestContext

Question

我正在使用 Citrus Java DSL 测试 REST 服务。我想保存响应中的数据以进行高级操作。根据文档，我应该使用 Citrus 测试上下文来实现此目的。

我尝试使用 CitrusResource 注释注入(inject) TestContext:

@CitrusResource
private TestRunner runner;

@CitrusResource
private TestContext context;


@When("^service sends request to get all orders$")
public void get_Orders() {
    runner.http(action -> action.client(httpClientName)
            .send()
            .get(basePath));   
}

@Then("^Service gets response with preflight id: \"([^\"]*)\"$")
public void verify_Orders(String preflightId) {
        runner.http(action -> action.client(httpClientName)
            .receive()
            .response(HttpStatus.OK)
            .contentType("application/json;charset=UTF-8")
            .extractFromPayload("$[*].styleId", "ids")
            .validate("$[*].styleId", everyItem(not(isEmptyOrNullString())))
            .validate("$[*].styleId", hasItem(preflightId)));

    String ids = context.getVariable("${ids}", String.class);
}

但出现空指针异常

1 Scenarios (1 failed)
4 Steps (1 failed, 1 skipped, 2 passed)
0m5.541s

java.lang.NullPointerException

此外，我尝试在所需方法中创建新的 TestContext

@CitrusResource
private TestRunner runner;

@CitrusResource
private TestContext context;


@When("^service sends request to get all orders$")
public void get_Orders() {
    runner.http(action -> action.client(httpClientName)
            .send()
            .get(basePath));   
}

@Then("^Service gets response with preflight id: \"([^\"]*)\"$")
public void verify_Orders(String preflightId) {
TestContext context = new TestContext();
        runner.http(action -> action.client(httpClientName)
            .receive()
            .response(HttpStatus.OK)
            .contentType("application/json;charset=UTF-8")
            .extractFromPayload("$[*].styleId", "ids")
            .validate("$[*].styleId", everyItem(not(isEmptyOrNullString())))
            .validate("$[*].styleId", hasItem(preflightId)));

    String ids = context.getVariable("${ids}", String.class);
}

得到了

com.consol.citrus.exceptions.CitrusRuntimeException: Unknown variable 'ids'

    at com.consol.citrus.context.TestContext.getVariableObject(TestContext.java:158)
    at com.consol.citrus.context.TestContext.getVariable(TestContext.java:133)
    at com.consol.citrus.context.TestContext.getVariable(TestContext.java:122)

你能帮我解决一下吗？

我不熟悉 Citrus，并且不确定您指的是哪个文档。要在 Cucumber-jvm 中的步骤之间共享状态，建议使用依赖注入(inject) (DI)。使用 Cucumber 进行 DI 有多种选择，包括 Spring、Guice 和 PicoContainer。后者是一个轻量级 DI 框架，如果您不使用不同的 DI 框架，这可能是最好的选择。
