Testing Camera and Gallery Intents with Espresso

When you have screens within your Android app that have camera and/or gallery features with some screen changes (views, labels or buttons that appear/disappear, etc) and you need to write some Espresso tests for those features/screens there are a couple of helpers that Ive been using and I want to share with you all.Granting PermissionsWhen you are using the Camera within your app, you need to grant some permissions in the device in order to read/store a photo. These permissions are asked in runtime an usually are related to READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE.

Thus, the GrantPermissionRule allows granting of runtime permissions on Android M (API 23) and above and when applied to a test class this Rule attempts to grant all requested runtime permissions.@get:Rulevar mRuntimePermissionRule = GrantPermissionRule.grant(android.

Manifest.permission.WRITE_EXTERNAL_STORAGE)This Rule is usually used to grant runtime permissions to avoid the permission dialog from showing up and blocking the Apps Ui, and according to official documentation:As per this rule will automatically grant READ_EXTERNAL_STORAGE when WRITE_EXTERNAL_STORAGE is requestedGallery TestThe code to test when a gallery icon is clicked in the app, then an image is picked and shown in the screen:The first thing here is that I have a helper method (CameraAndGallery.

savePickedImage) that first saves an image (for brevity the ic_launcher icon) that is going to be used in the test as a local file visible for the test:The activity parameter comes from the ActivityTestRule:@get:Rulevar mActivityTestRule = IntentsTestRule(MyActivity::class.java)Then I create an ActivityResult object (like a mock but for Android Intent) that is going to be used by the Espresso Intents matcher (to match and validate the outgoing intents):val imgGalleryResult = CameraAndGallery.createImageGallerySetResultStub(mActivityTestRule.

activity) intending(hasAction(Intent.ACTION_CHOOSER)).respondWith(imgGalleryResult)The secret here is to ask for the file previously saved and finally used as the result.

Note: To work with espresso intents, we must to add this dependency to apps build. gradle file:androidTestImplementation androidx.test.

espresso:espresso-intents:$espressoVersionFor the test we are writing, lets asume that the image picked from the Gallery, we are setting it in an ImageView that is visible for the user, then the final part of the test is to check that the image is displayed (method hasImageSet()):onView(withId(R.id.auctionphotos_bigimage_viewer)).

check(matches(hasImageSet()))Camera TestSimilar to Gallery Test, the test to get an image from the device Camera follows the almost the same steps, but in this case an image doesnt need to be saved before, only mock the result of the camera:The mocked capture result as follows:The resulting image is going to be taken by the intent:intending(hasAction(MediaStore. ACTION_IMAGE_CAPTURE)). respondWith(imgCaptureResult)And with that we can check if the image was taken and displayed:onView(withId(R.

China's biometric industry, especially in the field of fingerprint identification technology, has entered a mature development period, but its application in the financial field is still in the initial stage of exploration. In a variety of identification methods, compound biometric technology is widely favored.???? China's biometric industry, especially in the field of fingerprint identification technology, has entered a mature development period, but its application in the financial field is still in the initial stage of exploration. In a variety of identification methods, compound biometric technology is widely promising. The Research Report on the development trend of China's third-party payment industry from 2017 to 2018 points out that the competition among third-party payment institutions has gradually evolved from pure product form competition to business model competition, and will move to ecological construction in the future. Before the ecological construction, the relevant enterprises have made brilliant plans, hoping to gain the advantage in the competition, taking the initiative, such as WeChat's choice of payment to attack big data, while Alipay vigorously develops biometric technology. Many people may ask that biotechnology has become more popular in daily operations. Even if it goes wrong, the impact is not great, but is its application in the financial field really reliable? In fact, biometric technology has long been applied in the financial field, and fingerprint identification is a more mature representative. As an advanced high-tech prevention and management means, face recognition control system is widely used in important places with high security requirements such as banks and financial institutions because of its high security, wide application and extremely convenient use and management. The system has become an important symbol that the security technology has entered a new generation of biometric intelligent era. From another point of view, the entry of biometric technology into the financial field is also driven by market demand. In recent years, with the Internet of traditional financial services and the emergence of new Internet financial services, the demand for user identity verification and authentication has increased rapidly. People are more inclined to safe, reliable and convenient electronic identity authentication technology, which has also become the focus of the industry, and biometric technology just conforms to this trend of the market. However, there are many loopholes in a single identification technology, which is also the reason why many users are worried. For face recognition, the accuracy of image recognition is very important to the effectiveness of machine learning and executing user instructions, and it is also a prerequisite to ensure the wide application of face recognition. However, the development of face recognition technology is not mature, and there is still a great risk of misjudgment in practical applications. In addition, the development trend of face recognition and big data fusion makes face recognition an important carrier for collecting massive data and generating key basic information, which greatly increases the risk of data leakage; Moreover, there is still a lack of corresponding management mechanism for the collection, storage and use of personal image data, and personal privacy is easy to be exposed in public. In addition to face recognition, biometric technologies such as fingerprint recognition, palm geometry recognition, iris recognition and retinal recognition have their own defects. This is why biometrics cannot end the era of cryptography in a short time. So, how can biometrics improve its own security? On the one hand, technology research and development is also a way that is now accepted by the public and applied - composite biometrics. Composite biometric recognition combines a variety of biometric technologies such as fingerprint recognition, face recognition and iris recognition. It has more advantages than single feature recognition. It can not only identify a comprehensive biometric system with different biometrics, but also effectively solve the problems of non universality, fraud, invalidity and inaccuracy in identity authentication. Ant financial service adopts multiple biometric technologies including face, fingerprint and eye pattern to ensure the safety of customers' funds. Industry insiders said that with the continuous expansion of application fields, the new generation of biometric technology will lead the transformation of single biometric mode to composite biometric with its unique characteristics. Whether in security, finance or other fields, composite biometric will gradually become the mainstream of biometric field.

"Unattended" Has Become the Development Trend of the Parking Lot Industry, but the Safety Problem st
Almost every family has a car. Today, parking space has become a scarce thing. With the improvement of people's living standards, cars have become a priority for travel. The continuous growth of car ownership has increased a lot of pressure on urban traffic. The following problems are difficult parking and few cars. In order to solve this problem, the concept of "smart parking lot" has been proposed and widely used in various large parking lots. Of course, the continuous growth of car ownership has also driven the development of the parking industry. In the previous parking spaces, special people would control the fluctuation of the stop bar, guide vehicles to enter and charge parking fees. With the increasing scale of urban parking lots and the complexity of service vehicles, the efficiency and reliability of manual management have been difficult to meet the requirements put forward in management. At this time, the use of scientific and technological means to realize the intelligent management of vehicles came into being, and unattended parking lots are rapidly popularized. Advantages: 1) high recognition rate - it realizes the free card collection and charging function of entrance and exit license plate recognition. Combined with vehicle model and color recognition, the automatic recognition accuracy of entrance and exit charges reaches more than 99.5%. 2) Highly integrated - the integrated license plate recognition machine integrates license plate recognition, electromechanical control, soft ground sensing trigger, recognition area setting, network communication and terminal RS485 protocol control, so that one network cable and one power cable can complete the wiring. 3) 100% pass - the intelligent hardware recognition control system of the integrated license plate recognition machine and the intelligent fuzzy error correction matching function of the parking management system software complement each other to ensure 100% pass at the entrance and exit. 4) Fast traffic - the current situation of large traffic flow and frequent and dense vehicles. The vehicle management system with pure license plate recognition and charging can meet the rapid traffic of all vehicles and realize the non-stop admission of vehicles. 5) Unattended - minimize the number of parking lot managers through intelligent entrance operation. The intelligent charging system can automatically charge and reduce the work intensity of parking lot managers. The license plates captured by the exit vehicles and the entry vehicles are directly matched and retrieved, and the displayed exit charging interface realizes rapid charging. When the charging amount is zero, the gate can be opened automatically without charging operation, reducing the workload of toll collectors. 6) diversified charging mode: according to the car park management, we can realize cash payment, WeChat / Alipay mobile payment, payment machine self service payment, central station charging, bar code coupon payment, value payment, official account payment, no sense payment and other charging methods, and support the setting and inquiry of the privilege / free reason. 7) Humanized management mode - when fixed vehicles are not parked in the garage according to the regulations, the system will automatically charge according to the temporary parking charging standard; A car owner can hang three license plates and park any car at the same time, which is convenient for car owners and management. 8) Rigorous management means - capture pictures and license plate numbers of all vehicles in and out. Temporary vehicles are automatically matched in and out, and the temporary parking fee is automatically calculated. In case of free release under special circumstances, there is a selection record of free reasons. 9) Terminal hardware recognition technology - the license plate recognition link in hehao parking lot system is completed by the camera. Similarly, the validity of license plate and the issuance of gate opening command are also completed by the camera, which greatly reduces the dependence on the network and server. Although unattended parking has become the general trend today, there are still potential safety hazards. Whether the parking space induction recognition system can ensure that one car can stop, how to collect the parking invoice, and how to pay if there is no cash... Among them, there is also the most important issue, safety, which is the most concerned point. For facilities and equipment, safety protection, daily inspection and maintenance of equipment, lighting, fire protection, communication, monitoring and other problems in the parking lot, personnel are also required to conduct regular troubleshooting and maintenance, ensure the safe and effective operation of facilities and equipment, and solve emergencies.

The intelligent parking lot charging management system can realize different charging methods for different types of vehicles. If it is a temporary vehicle, the owner can take the card from the ticket box of the parking lot charging system installed at the entrance. After taking the card, the intelligent gate will open automatically. The owner at the exit only needs to submit the temporary card taken at the entrance to the administrator, The parking lot charging management system will automatically retrieve the parking information of this temporary card, and the payment amount will be automatically displayed on the charging display screen. People only need to pay according to requirements. For users handling monthly or annual cards, as long as the parking lot charging system recognizes the card information at the entrance, the gate can be opened automatically, and the card is also recognized at the exit, and the gate can be released automatically. As the intelligent parking system has corresponding applications in various large or super large commercial toll parking lots (airports, stadiums and exhibition centers), small and medium-sized commercial toll parking lots (supporting hotels, office buildings, shopping malls and theatres), community parking lots, and different parking lots have different requirements for system software and hardware. The traditional car parking management system only solves the problem of entrance and exit control, which is beyond the reach of parking guidance, car search, rapid access and other functions in the parking lot. In addition, there are some problems in the link of charging, such as single payment method, low efficiency of manual management, charging loopholes and so on, Not to mention the overall system integration and optimal allocation of resources of the parking lot. At ordinary times, there are many faults in the parking lot system equipment, such as the button does not start, the lever jumps, the vehicle entry and exit records are incomplete, the card swiping response is slow, and there are more faults in thunderstorm weather. Therefore, more and more security markets have introduced intelligent car parking management system equipment, which not only solves many fault problems, but also is very convenient to operate.
