用spock对spring云网关过滤器进行单元测试

chain.filter(exchange).then(<a mono relevant to response>)

当我试着用斯波克测试的时候 然后

过滤器本身:

@Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
    return chain.filter(exchange)
            .then(refreshCookiesMono(exchange));
}

private Mono<Void> refreshCookiesMono(ServerWebExchange exchange) {
    return Mono.fromRunnable(() -> {
        //interactions with *exchange* and *chain*
    });
}

尽管最终0*,但该测试通过:

@Subject
CookieFilter cookieFilter = new CookieFilter(cookieHelper)
...
ServerWebExchange exchange = Mock ServerWebExchange
GatewayFilterChain chain = Mock GatewayFilterChain
Mono<Void> mono = Mock Mono

...

def "cookieFilter refreshes the cookie with a new value"() {
    given:

    when:
    cookieFilter.filter(exchange, chain)

    then:
    1 * chain.filter(exchange) >> mono
    0 * _
}

但在我调用的代码中 。然后 从单声道返回 .过滤器

为什么不 单声道。然后() 考虑到了吗?当然,当我尝试测试所有底层逻辑时,spock找不到交互。
