Method and System for Compliance Testing in a Cloud Storage Environment

FIELD OF INVENTION

0001The invention relates to the field of software testing, and more particularly to compliance testing within a cloud computing network.

BACKGROUND

0002Cloud storage nowadays has become one of the convenient ways of data storage and data sharing. There are various vendors that offer cloud storage services like web hosting besides providing scalable infrastructure for better performance. Amazon's cloud services include Simple Storage Service (Amazon S3), the Amazon cloud drive. Similarly Microsoft has its own cloud storage services like Sky Drive, Windows Azure and similar such services.

0003However there are a few major challenges faced by end customers in existing cloud storage services. One of the major challenges is that there is no way for a cloud storage service provider to directly migrate customer data to another cloud storage service provider. If a service goes down, the hosting company must return the data to its customer, who then must find another provider or revert back to storing it locally. This is because the API's are specific for each vendor. Moreover there are no rules and regulations for data deletion. Further the financial aspects related to each of the cloud storage offered to end-customers are different for each vendor.

0004In the state of art there have been attempts to check performance and conformance testing while deploying solutions on the cloud storage. One of the prior art discloses about the SNIA standards and illustrates on how “capabilities” gets implemented. However there have been rare attempts for compliance testing as proposed in the invention.

0005For resolving these challenges, Storage Network Industry Association (SNIA) has come up with cloud standard APIs known as Cloud Data Management Interface (CDMI) which helps client in moving data from one cloud vendor to another cloud vendor without the pain of recoding to different interfaces. With this standard way of billing and using CDMI, a customer can compare capabilities of different Cloud storage's vendors. SNIA has a technical working group (TWG) for developing these standards.

0006CDMI needs to be implemented by the cloud vendors as a separate module for enabling the invention as described in the detailed description. However there is no such existing technology that assists a CDMI enabled cloud vendor to perform compliance testing of CDMI module implemented by the storage server. Thus a need for developing an automated test suite for CDMI specification exists.

0007Enterprises using API-based vendor proprietary cloud storage solutions face a challenge of vendor lock-in owing to diverse and vendor-specific solutions. It is therefore imperative to adopt industry-standard-interface CDMI-based solutions, which facilitate interoperability between cloud storage solutions through vendor neutrality. Since, CDMI-based specifications offer multiple Cloud storage use cases such as Cloud-to-Cloud migration, and also provide a functional application interface to create, retrieve, update, and delete data elements from the Cloud, it is worthwhile to introduce a solution that for which the CDMI specification forms a base and depending upon it compliance testing of data within a cloud computing environment is performed.

0008In the light of the above mentioned challenges a need is exists for a comprehensive solution that perform the compliance testing of CDMI module implemented by the Storage Server.

OBJECTIVES OR THE INVENTION

0009The principle objective of the invention is to provide a solution for compliance testing of CDMI (Cloud Data Management Interface) module as implemented by the storage server.

0010One other objective of the invention is to test the degree to which the Cloud Storage Server is CDMI compliant.

0011Yet another objective of the present invention is to provide automated test suite for CDMI specification.

0012Another objective of the invention is to verify the functionality check in case of any discrepancy observed.

Check for correct Http status code returned</li><li id="ul0023-0007" num="0118">5. Cleanup</li></ul>

0119The invention tests operations for both TLS (Transport Layer Security) and Non-TLS server on CDMI/Non CDMI objects. The process of compliance testing for CDMI and Non CDMI objects involves certain fixed steps. Initially a capability check is performed. If capability is supported by cloud storage provider then proceeds to next step. Next step involves authentication of the request (request can be CRUD), which when found authenticated transmits the Http request. After receiving the request, the server sends a response, wherein the response comprises of various response parameters that later gets subjected to a verification process. The response from the server broadly comprises of: <ul id="ul0024" list-style="none"><li id="ul0024-0001" num="0120">1. Http status code</li><li id="ul0024-0002" num="0121">2. Response Header</li><li id="ul0024-0003" num="0122">(e.g. Content-type, X-cdmi-specification version etc)</li><li id="ul0024-0004" num="0123">3. Response Message body—</li></ul>

0124Attributes of the cdmi object e.g. ObjectName, ObjectID, parentName, parentURI etc.

0125This response goes through a verification check to determine whether there is discrepancy in response or if any mandatory parameter's value is null or incorrect. If the response is OK, there is a check that whether the requested functionality is actually executed on the server or not. Lastly to terminate the operation cleanup is done.

0126Now referring to <figref idref="DRAWINGS">FIG. 1</figref>, the major components involved in the system and the overall architecture of the system is presented. The test harness is used to provide automated test suites for compliance testing of CDMI module implemented by the storage server. The test harness further comprises of a GUI that is used to invoke the test scripts and after execution of scripts reports are provided in portable document format (PDF). For each test scenario, multiple test scripts are present, and these test scripts receives data from the data files. Thus there are multiple test cases generated for a test script. The library module of the present invention has APIs for performing create, read, update, and delete operations on CDMI/Non CDMI objects. There are other functions also like—function for response validation and so on. The data files are used as input to the test scripts.

0127The invention involves two types of test cases in the test suite viz. Parameterized/Non Parameterized. Primarily the basic difference in executing the Parameterized and Non Parameterized test cases is that while the former requires use of data files, latter does not; rest all other steps of execution remaining the same. In one embodiments of the invention parameterized test cases are generated in the test suite. Before starting execution of test cases, initially all the capabilities supported by cloud vendor is fetched for whom testing for CDMI compliance needs to be performed.

0128The following steps are followed within each test case: <ul id="ul0025" list-style="none"><li id="ul0025-0001" num="0129">1. Capability check: If capability(s) corresponding to the test scenario, is supported by cloud storage provider then move to next step else the test case is not executed. This is implemented by using advanced use of JUnit so that only cloud vendor's capability based test cases are executed.</li><li id="ul0025-0002" num="0130">2. Create the prerequisite objects if required in a test scenario. For Instance—for scenario “Successful creation of data object” creation of container is prerequisite.</li><li id="ul0025-0003" num="0131">3. Set valid login credentials.</li><li id="ul0025-0004" num="0132">4. Steps 1 to 6 are executed until all fields of data file are read for having multiple set of input parameters. Hence multiple test cases are built for one scenario. <ul id="ul0026" list-style="none"><li id="ul0026-0001" num="0133">1. Fetch values from the data file and set in an input request.</li><li id="ul0026-0002" num="0134">2. Set Request Header.</li><li id="ul0026-0003" num="0135">3. Execute Http request.</li><li id="ul0026-0004" num="0136">4. Check for correct Http status code returned.</li><li id="ul0026-0005" num="0137">5. The response goes through a verification check whether there is discrepancy in response or if any mandatory parameter's value is incorrect or null.</li><li id="ul0026-0006" num="0138">6.

Finally cleanup is executed.</li></ul></li></ul>

0140In another embodiment of the invention non parameterized test cases are generated.

0141The following steps are followed within each Non Parameterized test case: <ul id="ul0027" list-style="none"><li id="ul0027-0001" num="0142">1. Capability check: If capability(s) corresponding to the test scenario is supported by cloud storage provider then move to next step else that test case is not executed. For this has been implemented using JUnit so that only cloud vendor's capability based test cases are executed.</li><li id="ul0027-0002" num="0143">2. Create the prerequisite objects if required in a test scenario. For Instance—for scenario “Successful creation of data object” creation of container is prerequisite.</li><li id="ul0027-0003" num="0144">3. Set valid login credentials.</li><li id="ul0027-0004" num="0145">4. Set required parameters in input request header/message body.</li><li id="ul0027-0005" num="0146">5. Execute Http request.</li><li id="ul0027-0006" num="0147">6. Check for correct Http status code returned.</li><li id="ul0027-0007" num="0148">7. The response goes through a verification check whether there is discrepancy in response or if any mandatory parameter's value is incorrect or null.</li><li id="ul0027-0008" num="0149">8. If the response is OK, there is a check that whether the requested functionality is actually executed on the server or not.</li><li id="ul0027-0009" num="0150">9. Finally cleanup is executed.</li></ul>

0151Referring to <figref idref="DRAWINGS">FIG. 2</figref>, the deployment scenario of the invention is illustrated. The invention is used to verify the degree to which a cloud storage system is CDMI compliant. It is the package containing test scripts for validating the response from CRUD operations performed on CDMI objects and checks for the cloud storage to be CDMI compliant. The check for the CDMI compliance works as follows.

0152Initially an input request is sent. The CDMI client sends http GET/PUT/POST/DELETE input request for the CDMI Object to CDMI server. In response to the input request the Server returns http response which has response header, http status code and http response body with mandatory parameters and optional parameters of the CDMI object, called as the output response. In the next step verification of the status code and the response body is performed where determination of successful execution of sent request made.

0153Referring to the system as shown in <figref idref="DRAWINGS">FIG. 3</figref>, it broadly comprises of a capability detection module for assessing if the capability for performing functionality is supported by the cloud service provider. Next an authentication step is performed that involves setting authentication parameter for the http request (request can be CRUD), after which the request header and request body are set in the http request and transmitted to the server by the execution module. Once the execution module executes the http request and transmits to the server, it receives the server response for further transmitting to the verification module. The response comprises of various response parameters that later gets subjected to a verification process in the verification module. The response from the server broadly comprises of: <ul id="ul0028" list-style="none"><li id="ul0028-0001" num="0154">1. Http status code</li><li id="ul0028-0002" num="0155">2, Response Header</li><li id="ul0028-0003" num="0156">(e.g. Content-type, X-cdmi-specification version etc)</li><li id="ul0028-0004" num="0157">3. Response Message body—</li><li id="ul0028-0005" num="0158">Attributes of the cdmi object e.g. ObjectName, ObjectID, parentName, parentURI etc.</li></ul>

0159This response goes through a verification check in the verification module to determine whether there is discrepancy in response or if any mandatory parameter's value is null or incorrect. If the response is OK, there is a check that whether the requested functionality is actually executed on the server or not. The verification module communicates with the library which has APIs for performing create, read, update, and delete operations on CDMI objects. There are other functions also like—function for response validation and so on. Lastly to terminate the operation cleanup is done.

Advantages of the Present Invention:

These algorithmic descriptions and representations are the tools used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities.

0165It should be kept in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the above discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “executing” or “verifying” or “validating” or the like, refer to the action and processes of a computer system, or similar electronic computing device having a processor and a non-transitory memory, among other components, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage or transmission.

WORKING EXAMPLE

0166The present invention also relates to an apparatus for performing the operations described herein. This apparatus may be specially constructed for the required purpose, or it may comprise a general-purpose computer selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a computer readable storage medium, such as, but is not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, and magnetic-optical disks, read-only memories (ROMs), RAMs, EPROMs, EEPROMs, magnetic or optical cards, or any type of media suitable for storing electronic instructions, and each coupled to a computer system bus.

0167The process presented herein in the working example is not inherently related to any particular computer or other apparatus, but for enabling the working of invention by a person skilled in the art. Various general-purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct a more specialized apparatus to perform the operations described.
