UITestを実行し、「Succeed UITest」としたい。

##　やりたいこと

UITestを実行したいが、Failed to get matchingとなってしまう。

##　試したこと

現在２つのテストを実行しようとしていますが、両方に

Failed to get matching snapshots: Application com.example.kazuki.CodeCheck-Test-Yumemi-2 is not runningが出てしまいます。

解決策を教えて頂きたいです。
(ビルドは成功します。)

swift
1    let app = XCUIApplication()
2    var repo: [[String: Any]] = []
3    
4    func testChecked() {
5        /// app配下のcellで指定したAccessibility IDに合致するものを全て取得する
6        let cells = self.app.cells.matching(identifier: "TestCell")
7        /// 取得できたセルの数の検査
8        XCTAssertEqual(cells.count, repo.count)  // Failed to get matching snapshots: Application com.example.kazuki.CodeCheck-Test-Yumemi-2 is not running
9    }
10    
11    func testTitleisEnabled() {
12        let label = XCUIApplication().staticTexts["RepositoryTitle"]
13        XCTAssertTrue(label.isEnabled) // Failed to get matching snapshots: Application com.example.kazuki.CodeCheck-Test-Yumemi-2 is not running
14    }

UITests全体コード

import XCTest

class CodeCheck_Test_Yumemi_2UITests: XCTestCase {
    
    let app = XCUIApplication()
    var repo: [[String: Any]] = []
    
    func testChecked() {
        /// app配下のcellで指定したAccessibility IDに合致するものを全て取得する
        let cells = self.app.cells.matching(identifier: "TestCell")
        /// 取得できたセルの数の検査
        XCTAssertEqual(cells.count, repo.count)
    }
    
    func testTitleisEnabled() {
        let label = XCUIApplication().staticTexts["RepositoryTitle"]
        XCTAssertTrue(label.isEnabled)
    }
    
    override func setUpWithError() throws {
        // Put setup code here. This method is called before the invocation of each test method in the class.
        
        // In UI tests it is usually best to stop immediately when a failure occurs.
        continueAfterFailure = false
        
        // In UI tests it’s important to set the initial state - such as interface orientation - required for your tests before they run. The setUp method is a good place to do this.
    }
    
    override func tearDownWithError() throws {
        // Put teardown code here. This method is called after the invocation of each test method in the class.
    }
    
    func testExample() throws {
        // UI tests must launch the application that they test.
        let app = XCUIApplication()
        app.launch()
        
        // Use recording to get started writing UI tests.
        // Use XCTAssert and related functions to verify your tests produce the correct results.
    }
    
    func testLaunchPerformance() throws {
        if #available(macOS 10.15, iOS 13.0, tvOS 13.0, *) {
            // This measures how long it takes to launch your application.
            measure(metrics: [XCTOSSignpostMetric.applicationLaunch]) {
                XCUIApplication().launch()
            }
        }
    }
}
