Alex Maltsev on Tap Into Mobile Application Testing (Jonathan Kohl) Alex Maltsev attached scretch.info to Tap Into Mobile Application Testing. The mobile market has increased exponentially in the last decade, in every way build machines, automated testing, application and web server updates, . tapping every visible button possible, filling in every text field on the screen – all of. In the paper we investigate the state-of-the-art mobile testing application installation on a real device, i.e., by a tap on the link in an email op.

Do you need to test applications on mobile devices but you aren't sure where to start? Or, are you a mobile testing veteran looking to find more ideas for your. Tap Into Mobile Application. Testing. Jonathan Kohl. This book is for sale at http:// scretch.info This version was published on. Tap Into Mobile Application Design. Jonathan design, project management and testing on mobile application projects for smartphones, tablets and wearables.
It is the right tool in the hands of a mobile app tester to automate testing for mobile phone devices connected with diverse mobile networks spread across different geo-locations. The commands comprising the scripts are readily available on the websites in the form of widgets. Test developers just need to click on the commands to add to the scripts and define its properties in the user interface. Perfecto Mobile testing tool works on image or text recognition. The generation of these scripts can be watched in the following videos. Test developers can easily install third Party applications or APK files on the remote devices using their Install widget.
To validate that the installed application enables other applications to perform satisfactorily, and it does not eat into the memory of the other applications.
To validate that the application resumes at the last operation in case of a hard reboot or system crash. To validate whether the installation of the application can be done smoothly provided the user has the necessary resources and it does not lead to any significant errors.
To validate that the application performs auto start facility according to the requirements. To validate whether the application performs according to the requirement in all versions of Mobile that is 2g, 3g and 4g. To perform Regression Testing to uncover new software bugs in existing areas of a system after changes have been made to them.
Also rerun previously performed tests to determine that the program behavior has not changed due to the changes. The general test scenarios for Performance Testing in a Mobile application are: To determine whether the application performs as per the requirement under different load conditions. To determine whether the current network coverage is able to support the application at peak, average and minimum user levels. To determine whether the existing client-server configuration setup provides the required optimum performance level.
To identify the various application and infrastructure bottlenecks which prevent the application to perform at the required acceptability levels.
To validate whether the response time of the application is as per as the requirements. To evaluate whether the battery life can support the application to perform under projected load volumes. To validate each of the required the CPU cycle is optimization To validate that the battery consumption, memory leaks, resources like GPS, Camera performance is well within required guidelines. To validate the application longevity whenever the user load is rigorous.
To validate the network performance while moving around with the device. To validate the application performance when only intermittent phases of connectivity is required. The following are the most crucial areas for checking the security of Mobile applications. To validate whether an application is not permitting an attacker to access sensitive content or functionality without proper authentication. To validate that the application does not suffer from insufficient session expiration.
To identify the dynamic dependencies and take measures to prevent any attacker for accessing these vulnerabilities. To prevent from SQL injection related attacks. To identify and recover from any unmanaged code scenarios. To ensure whether the certificates are validated, does the application implement Certificate Pinning or not. To protect the application and the network from the denial of service attacks.
To analyze the data storage and data validation requirements. To enable the session management for preventing unauthorized users to access unsolicited information.
To check if any cryptography code is broken and ensure that it is repaired. To validate whether the business logic implementation is secured and not vulnerable to any attack from outside.
To analyze file system interactions, determine any vulnerability and correct these problems. To validate the protocol handlers for example trying to reconfigure the default landing page for the application using a malicious iframe. To protect against malicious client side injections. To protect against malicious runtime injections. To investigate file caching and prevent any malicious possibilities from the same.
To prevent from insecure data storage in the keyboard cache of the applications. To investigate cookies and preventing any malicious deeds from the cookies. To provide regular audits for data protection analysis. Investigate custom created files and preventing any malicious deeds from the custom created files.
To prevent from buffer overflows and memory corruption cases. This includes passing user credentials, or other authentication equivalents.
This provides confidentiality and integrity protection. AES and appropriate key lengths check current recommendations for the algorithm you use e. Be very cautious in allowing self- signed certificates. Do not disable or ignore SSL chain validation.
This can be achieved by ensuring that SSL is only established with end-points having the trusted certificates in the key chain. Reference: Google vulnerability of Client Login account credentials on unprotected wifi -  4.
Implement user authentication,authorization and session management correctly Risks: Unauthorized individuals may obtain access to sensitive data or systems by circumventing authentication systems logins or by reusing valid tokens or cookies. It may be useful to provide feedback on the strength of the password when it is being entered for the first time.
The strength of the authentication mechanism used depends on the sensitivity of the data being processed by the application and its access to valuable resources e. For example, require authentication credentials or tokens to be passed with any subsequent request especially those granting privileged access or modification.
Note that random number generators generally produce random but predictable output for a given seed i. Therefore it is important to provide an unpredictable seed for the random number generator. The standard method of using the date and time is not secure. It can be improved, for example using a combination of the date and time, the phone temperature sensor and the current x,y and z magnetic fields.
In using and combining these values, well-tested algorithms which maximise entropy should be chosen e. IP location, etc Keep the backend APIs services and the platform server secure Risks: Attacks on backend systems and loss of data via cloud storage. Secure data integration with third party services and applications Risks: Data leakage.
Users may install applications that may be malicious and can transmit personal data or other sensitive stored data for malicious purposes.
In the European Union, it is mandatory to obtain user consent for the collection of personally identifiable information PII. This record should be available to the user consider also the value of keeping server-side records attached to any user data stored.
Such records themselves should minimise the amount of personal data they store e. Implement controls to prevent unauthorized access to paid-for resources wallet, SMS, phone calls etc. Logs should be protected from unauthorised access. Distributing apps through official app- stores therefore provides a safety-net in case of serious vulnerabilities in your app.
Carefully check any runtime interpretation of code for errors Risks: Runtime interpretation of code may give an opportunity for untrusted parties to provide unverified input which is interpreted as code. For example, extra levels in a game, scripts, interpreted SMS headers. This gives an opportunity for malware to circumvent walled garden controls provided by app-stores. It can lead to injection attacks leading to Data leakage, surveillance, spyware, and diallerware.
Be aware of privileges granted by default by APIs and disable them. Use the communication mechanisms provided by the OS.
