Bazel系列-bazel test 使用https(一)

bazel 提供了 unit test和ui test的rules

分别是:

ios_unit_test 和 ios_ui_test

但是当我们尝试用ios_unit_test 去写https网络请求的时候会出现请求失败的现象

如图

BUILD代码

objc_library(
    name = "User_test_library",
    testonly = 1,
    srcs = glob(["UserTests/*.m"]),
)

ios_unit_test(
    name = "User_test",
    minimum_os_version = "9.0",
    deps = [
        ":User_test_library",
    ]
)

UserTests代码:

#import 
#import 
@interface UserTests : XCTestCase

@end

@implementation UserTests

- (void)setUp {
}

- (void)testDown {
    NSLog(@"请求开始");

    XCTestExpectation *expectation = [self expectationWithDescription:@"异步加载 Person"];
    NSString *url = @"https://baidu.com";
    NSString *urlStr = [url stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlStr]];
    NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:
            ^(NSData *data, NSURLResponse *response, NSError *error) {
            NSLog(@"请求完成...");
            if (!error) {
                NSString * str  =[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
                NSLog(@"str-------------:%@",str);
                
                [expectation fulfill];
                
            } else {
                NSLog(@"error------- : %@", error.localizedDescription);
                [expectation fulfill];

            }

        }];
    [task resume];

    [self waitForExpectationsWithTimeout:5 handler:nil];

}

发现在unit的时候, 使用https报The certificate for this server is invalid错误 ,查阅资料, 都没有找到相关记载,于是翻看rules_apple 和xctestrunner 这两个rules是直接和ios_unit_test相关的两个rules

大致流程如下:

0.build_bazel_rules_apple 构建xctest ,tmp目录, workdir等,获取我们定义的参数, 替换模板,调用ios_test_runner.py

1.构建xctest_session类 ,保存rules_apple 过来的参数 ,bundle(xctest),app_path,work_dir然后处理传过来的的参数,拼装APP目录等, 用来构建_xctestrun_obj

2.session_obj ,调用

['xcrun', 'simctl', 'spawn', '-s’,’-arch’,’x86, '4418A866-2C5B-4C36-BC88-6A4C6895C40C', '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Xcode/Agents/xctest', '-XCTest', 'All', '/Users/username/Documents/bazeltest/tmp/test_runner_work_dir.XeXTe9/user_test/User_test.xctest']
