Software testing techniques are approaches you take towards running a test case. For example at the highest level you may take a black box approach or a white box approach to testing a piece of software. Where with a black box approach you don't understand the internals of the software you are testing but you do know what range of inputs the software can accept and from that you can deduce the expected results. With a white box approach you have a much better understanding of how the software works (perhaps you've been involved in a code review with the developers) and you can create your tests based on exercising the code knowing that the software should do x, y and z with the inputs.
Software testing tools however would be employed to help you achieve the approaches you plan to take with testing a piece of software. So taking the black box testing approach discussed above you may use a test data generation tool to help you create the inputs for your black box testing technique. Another example would be using a data comparison test tool to compare expected results with actual results once the tests have been exercised.
So in conclusion a test technique describes the approach you might take to test a piece of software, where as a software testing tool would be a method you employ to help you achieve the aims of the software test.

Software testing services companies use a variety of testing techniques to verify and validate software products, ensuring that they meet the user requirements, are of high quality, perform optimally, and are free of bugs and defects. Here are some of the common software testing techniques used by these companies: Functional Testing: Functional testing is one of the most important testing techniques used in software testing services company to ensure that the software meets the user requirements. This technique involves testing the individual functions of the software to ensure that they perform as expected and that the software's overall functionality is satisfactory. This testing technique involves testing the software's features, such as input validation, data manipulation, and output generation. Performance Testing: Performance testing is the process of testing the software's performance under different loads and stress conditions to ensure that it performs optimally. This testing technique involves testing the software's speed, scalability, and stability. Security Testing: Security testing is the process of identifying and eliminating potential security threats and vulnerabilities in the software product. This testing technique involves testing the software's resistance to hacking, viruses, and other security threats. Usability Testing: Usability testing is the process of testing the software's usability to ensure that it is user-friendly and easy to use. This testing technique involves testing the software's user interface, navigation, and ease of use. Regression Testing: Regression testing is the process of testing the software product after making changes to ensure that the changes do not introduce new defects or problems. This testing technique involves testing the software's existing functionality to ensure that it still works correctly. Automated Testing: Automated testing is the process of using software tools to automate the testing process. This testing technique involves writing scripts to automate the testing process, which helps speed up the testing process and minimize the risk of human error. By using these testing techniques, software testing services companies can ensure that software products are of high quality, perform optimally, and are free of bugs and defects. These companies use advanced testing tools and techniques to identify and eliminate potential issues in the software product, resulting in better user experience, increased customer satisfaction, and ultimately, business success.
Alpha testing is always performed by the developers at the software development site. acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.
verification: Are we doing the right system? validation : Are we doing the system right?
Systems Commissioning is the process of testing final versions of software, hardware and configuration in their final locations. Once completed, it is "Live" (Available for use) and will not require further testing.
Alpha Testing is always performed at the time of Acceptance Testing when developers test the product and project to check whether it meets the user requirements or not.Beta Testing is always performed at the time when software product and project are marketed.

There is no such difference. it depends on the experience and organization where you are working.
Static vs. dynamic testingSoftware testing is an investing conducted provides stockholders with information about the quality of product or service under test. Software testing can also provide an objective, view of the software to allow the business to appreciate and understand the risk of software implantation. Test techniques include, but are not limited to the process of executing a program or application with the intent of finding software bugs. There are large number of approaches of software testing.Reviews & inspections are called as static testing, whereas actually executing programmed code with a given set of test case is referred to as dynamic testing.Static testing can be omitted, and in practice often is.Dynamic testing takes place with the program itself used. Dynamic testing begin before the program is complete its execution in order to particular sections of code are applied to discrete function or modules. Typically techniques for this are using stubs / drivers or execution from a debugger environment.A static testing involves verification whereas dynamic testing involves validation. Together they help to improve software quality.Other methods of software testing:The box approachVisual testing
