In VHDL, the next statement or command or instance is generally selected using a clock pulse.
clk'event and clk = '1'
means rising edge of the clock.
clk'event and clk = '0'
means rising falling of the clock.
The statement written after this line executes after the occurrence of a rising or falling edge of a clock.
if (clk'event and clk = '1')
The above statement makes the next statement or command to execute for every rising edge of the clock. By applying a clock pulse with minimum time period, we can make the next command to be called.

What is a testbench in vhdl?
A Test Bench in VHDL is code written in VHDL that provides stimulus for individual modules (also written in VHDL). Individual modules are instantiated by a single line of code showing the port connections to the module. The correctness of the written program can be checked by writing the test bench. It is a collection of VHDL procedures and functions which allow the user to create their own scripting instructions for test stimulus. Designers manually design their test bench inputs to checks the output. The stimulus script or test case contains the instructions in a regular ASCII text file. The test bench VHDL package contains procedures to create instructions, read, parse and execute the test script.

Why should you use vhdl?
VHDL is a hardware description language. Its very purpose is to describe hardware in the form of a program. This program can be understood by the user and the system as well. By implementing the hardware as a code, it is easier to verify its functionality. Hence, to test hardware before it could actually be designed, we should use VHDL.
How vhdl is used?
VHDL is a hardware description language. The purpose of any HDL is to represent hardware as a program. We can write a program (code) for any digital circuit using VHDL. With the help of this code, the output of the circuit can be observed before actually designing it physically.

What is simulation in vhdl?
After writing the VHDL code, we wish to verify the code and its functionality. Verifying the code for syntax errors is called compilation. Later, applying the inputs and obtaining the outputs is called simulation. If we are not getting the desired output, we may check our code and re-compile and simulate.
